I presume all older issues are not valid anymore, otherwise you can find them on /StartingWithRoboRumbleOld or put them here below again.

Sweet. Much easier now thanks. How can I control how many battles are run at once? Or should I just setup a for loop in a batch file for that? --Miked0801

• Halfway the file "roborumble.txt" you'll find "NUMBATTLES=xx", there you fill in the number of battles fought before uploading results and quitting robocode. In the batch-file I have made an infinitive loop so my client can run unattended all night. -- GrubbmGait
• (Edit conflict) There are .txt files for each type of rumble - roborumble.txt, meleerumble.txt, and teamrumble.txt - in the 'roborumble' directory. The "NUMBATTLES" controls how many are run before uploading, "BATTLESPERBOT" is the minimum number of battles a bot needs before it stops getting priority, and "USER" is just to identify yourself in the logs and such. I have mine with "ITERATE=NOT" and I do use a shell script that loops to keep it running. -- Voidious

this bash script will be good for unix "roborumbler". Run forever battles, it catch standard and error stream and put it to a file in the directory ./log/tempNUMBER_OF_BATTLE.txt (the script have to be in the roborumble directory). For Linux: save it to a file in the roborumble directory, right click and set the file executable, create a directory called "log", then run the script from shell:

#!/bin/bash

echo #  new line
count=0
while [ "$var1" != "fine" ]     #  forever
do
  let "count=count+1"
  echo "battle n: " $count
  sh roborumble.sh &> ./log/temp$count.txt
  echo
done  

exit 0

p.s.: it's very useful for catch error, someone can traslate the script in windows's dos? Asdasd

Wow - is 256MB still the default for the rumble? Why not at least 512, if robocode's default itself is 512? -- Simonton

I'm not sure - maybe because the GUI takes a lot of memory? -- Skilgannon

Ehh, the GUI shouldn't, not compared to many adaptive bots (particularly log targeting). Personally I always set 512MB in the rumble, and the only time I've had an out of memory problem with 512MB was when some particularly memory-heavy team (can't remember which one) was going. Personally I'd support defaulting to 512MB, at least for teams/melee, if Fnl is listening :-) -- Rednaxela

Can someone please zip a new update, i've unzipped the archives above and still get a ton of "Ignoring xxx..." message because they weren't download...thank you! (or even better someone start a new repository and put the zipped bots there...) --Starrynte

RoboRumbler

I didn't know where to post this, but I guess the talk section is always good enough. I created an Java Application called RoboRumbler to help controlling the resources RoboRumble uses. It's basically an application to let me work and run RoboRumble at the same time, I further explain it in it's page if anyone is interested. --zyx

Hmm, I'm curious about this. How does it account for the fact that RoboRumble is highly sensitive to the amount of CPU allocated to it? (i.e. other apps taking lots of CPU can make bots skip turns and potentially give very wrong results). If this limits the CPU allocated to RoboRumble, does it correctly make sure the constant for the time robots get per turn is increased suitably? (P.S. on the new wiki you can use --~~~~ or the signature button to sign your messages with time/date easily. Personally I'd recommend it because it makes it possible to look back at conversations and know when they happened. :)) --Rednaxela 21:45, 26 November 2008 (UTC)

Right now the application is not intended to work with CPU intensive applications, it basically runs them in the same way as they would normally do, but allows you to run then from time to time, and then forever by itself again and stuff like that. So you could be working in the machine, but not hogging the CPU yourself, you can set it to have a few battles and then sleep for 20 minutes. You could be writing some code(I did it to work on my thesis in the mean time), but not execute it until the RoboRumbler goes to sleep. Then you would have those 20 or any other amount of time to use the whole CPU when no rumble battles are running, so you could compile and test your application, and then, when the rumble is about to start again, you lower your activity. And when you are heading to your bed, set the sleep time to 0 and let it rumble without stop.

Hopefully it will grow to a system that doesn't need for the user to be careful, but right now is the best I have. I was doing the same thing but manually, I ran the rumble battles while I was writing stuff, waited for it to finish so I could ran my application and then set the rumble again. But in no moment my idea was to really lower the CPU usage for RoboRumble during battles, but to have some deterministic break times when I could use the computer. (P.S. Thanks about the --~~~~, I saw it before in your post, but thought you wrote it yourself, and seemed like to much work) --Zyx 23:44, 26 November 2008 (UTC)

stable rumble client

Are the stable rumble client 1.5.4 and, 1.6.0 or 1.6.0.1? someone have tested the new robocode version? --lestofante 15:44, 10 December 2008 (UTC)

I know 1.6.1.4 is stable (some earlier 1.6.1.x versions were bad), with a minor aesthetic bug that it sometimes spams the "Round 31 initializing...." to stdout but that doesn't affect the battles or the uploading so it's good for RR. Additionally, as of 1.6.1.4 the ITERATE option works properly again, so external loop scripts shouldn't be needed. I plan to test 1.6.2 Beta 2 some time but haven't done that yet. --Rednaxela 20:10, 10 December 2008 (UTC)

RUNONLY

I have RUNONLY=NANO in meleerumble, yet it still runs battles with tons of non-nano bots. 1) will this affect rankings improperly 2) how do you get it to run only nanos...as runonly is supposed to do (using version 1.6.0.1) --Starrynte 00:59, 3 April 2009 (UTC)

• I've never tried these modes so don't know how well they work. I'm pretty sure RUNUNLY=SERVER is the only way to guarantee full pairings, since that's the mode where the client uses priority battles sent by the server. Also, I think the client considers nano pairings in melee to be any matchups between two nano bots, even if there are other sizes in the same battle -- which means you don't need a battle with 10 nanos in order to get meleenano results. That's why ntc.Opposite's nano results are up to 600+ already. --Darkcanuck 01:18, 3 April 2009 (UTC)

Questions from Positive

Hey, I'd like to contribute, but need some help. I've followed the instructions on this page (I used version 1.6.1.4). But what's the correct configuration for meleerumble.txt for Darkcanuck's server? Also: Can I safely quit the roborumble client when I need my CPU back? Is there something else usefull to know/do before running? :) --Positive 16:40, 17 July 2009 (UTC)

I think you can just replace the domain with darkcanuck.net, but my full URLs are:

• PARTICIPANTSURL=http://robowiki.net/w/index.php?title=RoboRumble/Participants/Melee
• UPDATEBOTSURL=http://darkcanuck.net/rumble/RemoveOldParticipant
• RESULTSURL=http://darkcanuck.net/rumble/UploadedResults

Yes, run the client as much or as little as you like, of course. =) Hmm, one issue comes to mind: the bots using Robocode Repository ids will fail to download, I think. I fixed the URLs on the 1v1 list and some on the Melee list, but still lots of ids there. Running the 1v1 client to download bots first might get a lot of the missing ones. I'll try and get that fixed today.

--Voidious 16:58, 17 July 2009 (UTC)

Hrm, well it seems like it should work, with Portia it did, or did you have to add it manually? I could make a script and change all lines with "ROBOTNAME,NUMBER" to "ROBOTNAME,http://www.robocoderepository.com/BotFiles/NUMBER/ROBOTNAME.JAR" --Positive 17:11, 17 July 2009 (UTC)

Hmm, now I'm not sure, really. I don't think I grabbed Portia manually. Feel free to update the list yourself, if you want, I did exactly as you said using regular expression find/replace in my text editor (TextWrangler). I'll get to it later today if you haven't yet. --Voidious 17:24, 17 July 2009 (UTC)

Hmm, I tried it, and it's not that easy. For example, the pure converted form of TheArtOfWar changes from "tzu.TheArtOfWar 1.2,689" to "tzu.TheArtOfWar 1.2,http://www.robocoderepository.com/BotFiles/689/tzu.TheArtOfWar 1.2.jar". But I don't know what the actual download link is. (It's not "tzu.TheArtOfWar_1.2.jar" either). Any downside to just activating roborumble and seeing what happens? --Positive 17:54, 17 July 2009 (UTC)

It seems TheArtOfWar was an exception, I'll replace the original with the new in a few moments. :) --Positive 18:06, 17 July 2009 (UTC)

Cool. I'm not sure what's up with that, but I was thinking, "I swear I used that same format for the 1v1 list and it worked." =) Also, Darkcanuck was kind enough to post all his rumble bots here: [1], so you can grab any missing ones. (I didn't mention before because it's not a great way to get all of them.)

One of us should post an updated .zip of rumble bots as a base point for new RoboRumblers... there are a few old ones posted around the wiki, but I can never remember where. The hurdle with that is cleaning out all the multiple versions of certain bots before zipping.

--Voidious 18:14, 17 July 2009 (UTC)

I found the .zip here: RoboRumble/Starting With RoboRumble. That zip is pretty complete, the message I got only showed a few missing:

Feel free to replace links in the participant lists to those on the rumble server (if they exist). I'm not planning to remove any of those bots, and will periodically copy new ones over from my client. --Darkcanuck 18:53, 17 July 2009 (UTC)

I'll see if I can post new versions of the participants zipfiles for one-on-one and melee this weekend. Last time I had trouble getting it online as my webspace (20Mb) was full. --GrubbmGait 13:00, 18 July 2009 (UTC)

You may contact me or Voidious to put them on my or his webspace. I don't know how much Voidious has, but I have around 1.1GB free. » Nat | Talk » 14:33, 18 July 2009 (UTC)

Just curious, isn't it possible to upload the zipfile to this wiki? It seems the right place to put it. A complete zip for one-on-one would be approx 18 Mb, for melee approx 8 Mb. Just need to bring up my rusty Perl knowledge so I don't have to sort out the current participants manually. --GrubbmGait 11:30, 19 July 2009 (UTC)

You must have access to this server to do that. I don't know if you have it or not. Because the wiki only accept .png, .gif, .jpg and .jpeg files. I agree with you that the wiki is the right place to upload them; but if you can't, feel free to contact me, my email is on my user page. » Nat | Talk » 11:41, 19 July 2009 (UTC)

It's not possible for me, max download is 2Mb. Melee is 6.5Mb, full one-on-one 16.8Mb. I'll try to put it on my own space first. --GrubbmGait 12:51, 19 July 2009 (UTC)

Friendlier Starting?

We've always had this problem, but now I'm the victim instead of the perpetrator! "Getting Started" really should be ... let's say three steps at the most: 1) Install robocode in a fresh directory. 2) Apply this patch (that takes care of config). 3) Download these bots (all in one file). And really, (2)'s config should be packaged w/ robocode as long as the rumble itself is. In the mean time, perhaps update the instructions to point the config files to the correct server? I followed them, and unless I missed it every time I read through them, it never says to change the URLs to something other than http://rumble.fervir.com/... What should they be? I tell ya - a guy just wants to help out his old community and has to go to all this trouble ... --Simonton

Because the newer version isn't stable yet, we don't use the newer version of Robocode in RoboRumble. Starting from 1.7.1, you just install it, edit a little config, download bots and let it runs. We can't package the (2) with Robocode though, it is older version. This feature has already been implemented in 1.6.2 and later.

And I must say, we are close to the new stable release. If we change to 1.7.1.x, we must all change (diff movement rule) our client. » Nat | Talk » 14:21, 5 August 2009 (UTC)

Oh, Simonton? Nice to see you still randomly visit the wiki. I'll update it soon. » Nat | Talk » 14:23, 5 August 2009 (UTC)

(Edit conflict) Yeah, we can use all the help we can get, so this should be as easy as possible. I think you just replace the rumble.fervir.com domain with darkcanuck.net. For Melee, the URLs are:

• PARTICIPANTSURL=http://robowiki.net/w/index.php?title=RoboRumble/Participants/Melee
• UPDATEBOTSURL=http://darkcanuck.net/rumble/RemoveOldParticipant
• RESULTSURL=http://darkcanuck.net/rumble/UploadedResults

I think just the participants URL would lack "/Melee" for 1v1, but I'm not at my rumble computer right now to confirm. And yeah, like Nat mentioned, we only allow 1.6.1.4, with the patched .jar, for RoboRumble clients right now. --Voidious 14:25, 5 August 2009 (UTC)

I think he know what to do, he just pointed out that the newbie won't understand it at all =) » Nat | Talk » 14:38, 5 August 2009 (UTC)

As I rewrote the starting guide, I noticed some funny thing. It used to say that:

(Sorry, a little dirty) ... on your first time you can start robocode with ...

Sorry, for anyone who didn't find this amusing at all. And feel free to delete this if you think it shouldn't be here. » Nat | Talk » 14:38, 5 August 2009 (UTC)

How about this... as soon as I get home from work, I'll make a patched robocode-setup-1.6.1.4.jar (maybe renamed robocode-rr-setup-1.6.1.4.jar or something), which includes the patched robocode.jar, fixed config files, AND the jar files of all robots currently in roborumble, that'll solve this :) --Rednaxela 16:41, 5 August 2009 (UTC)

That's what basically Simonton asked. I don't think ALL robots in rumble is good idea, it is large! And the installation will take very long. It is better if you just do all thing, zip it, and upload. You don't want the desktop and start menu shortcut for RR client. » Nat | Talk » 16:48, 5 August 2009 (UTC)

The Roborumble Superpack is here! With this simple zip file, it is now virtually effortless to deploy a robocode installation suitable for your RoboRumble needs! I intend to update the Roborumble Superpack whenever a new version of robocode is approved for RoboRumble submissions, or the list of bots changes significantly. Cheers! :) --Rednaxela 02:08, 6 August 2009 (UTC)

I'm not sure having all the bots in the pack is such a great idea, as I think roborumble downloads them automatically, no? As long as they have to download it anyways, they may as well get the complete list instead of an old version ;) But having the pack will definitely help, it was a bit of a nuisance to get the old robocode when I was starting with it last week. Spinnercat 02:20, 6 August 2009 (UTC)

Awesome! Sure, you'll have to download the new versions for some of them, but probably 90% of the bots in that .zip are unlikely to ever change, so I like having the option to get them all at once. And some of us are still scarred from the days when the Robocode Repository would crash if you tried to actually download hundreds of bots in a row witha fresh RR client. =) --Voidious 02:28, 6 August 2009 (UTC)

Thanks, Red! Works great. --Simonton

No problem Simonton! Also, updated superpack zip, to fix the default memory limit on melee/team rumble to be 512M instead of 256M and 128M. Added the new Diamond version while I was at it as well since there was no reason not to. --Rednaxela 06:19, 6 August 2009 (UTC)

Error Running RoboRumble

Hi, i get the following error when tring to run roborumble.bat with version 1.6.14 (newest version of RoboRumble works great though):

This is why. You missed a comma, which broke all main rumble clients momentarially :) --Rednaxela 13:13, 13 August 2009 (UTC)

Woops! I'm sorry about that. Thanks for the help! --Rsim 13:20, 13 August 2009 (UTC)

Superpack update 20090814

Updating the RR superpack now. The changes are:

• Fully updated collection of rumble bots
• robocode.jar being patched for a bug (See Talk:RoboRumble/Reported Problems#IllegalThreadStateException)
• AND the shiny new TwinDuel, Rumble Edition.

Enjoy :) --Rednaxela 03:51, 15 August 2009 (UTC)

Does that .jar have Darkcanuck's patch? I haven't test it yet, but I want to be sure. » Nat | Talk » 04:44, 15 August 2009 (UTC)

Yep, it does. It's based upon the old superpack, just with the fixed robocode.jar (already had Darkcanuck's roborumble.jar), updated robots, and the twinduel stuff. --Rednaxela 05:03, 15 August 2009 (UTC)

Argh! I read "robocode.jar" as "roborumble.jar". Sorry =) » Nat | Talk » 05:18, 15 August 2009 (UTC)

Haha, don't worry much about that. I've sometimes been getting those two mixed up when reading/typing things myself. --Rednaxela 05:28, 15 August 2009 (UTC)

A few questions

Hi, I want to contribute (and if I find some time, also to write an own robot). I already uploaded some results, but three questions came up:

• If in roborumble.txt DOWNLOAD is set to YES, everytime I'm starting the program it's trying to download some missing bots which takes quite some time without any success. I took a look at the /robots page by Darkcanuck, but those ones are not shown there unfortunately (e.g. ar.horizon.Horizon 1.2.2). With ITERATE=YES it works kinda well, but still it is disturbing me a bit :-)
• Is there a way to actually "watch" the battles fought when running the rumble?
• Is it "allowed" to change the NUMBATTLES variable to something like 100?

And by the way, is there a way to automatically add the time and date behind my nick? --Kenran

Welcome, and some answers:

• Alas not, if the repository is down and Darkcanuck does not host them (yet), the client is not able to fetch them.
• The client uses robocode without userinterface, so it's not possible to watch them.
• it is allowed to change NUMBATTLES to whatever you want
• you can use --~~~~ or click the most-but-one right option at the topbar (signature with timestamp)
• It is wise to use separate installs for roborumble, meleerumble and own development. This way they are not interfering with eachother.

--GrubbmGait 13:58, 28 November 2009 (UTC)

Thank you! What could cause problems if I developed my bots within the install that I also use to run roborumble? Don't get me wrong, I believe in what you said and will use a separate robocode folder for development. I'd just like to know :-)
--Kenran 14:10, 28 November 2009 (UTC)

If you don't run the roborumble and Robocode at the same time, there is no problem unless you count you have to wait for a long time each time you started new battle to wait for robot database to be reloaded. If you run them at the same time, problems may occur especially when the Robocode and RoboRumble are running the same robot at the same time. This result in weird, unexpected result. Trust me, I have done it before, and somehow RoboRumble result injected into MeleeRumble result. --Nat Pavasant 15:57, 28 November 2009 (UTC)

Running both at the same time is a bad idea anyway. Both like to eat up lots of CPU and of course other things using lots of CPU can cause skipped turns. Even on a dual core machine I don't think it would be trustworthy to run two instances of robocode at once, since robocode with GUI does graphics painting in a seperate thread from running the bots, and that can also take substantial CPU. I'd only really trust running two instances at once on quad core machine. --Rednaxela 16:03, 28 November 2009 (UTC)

I strongly agree that people should mind their CPU consumption on any machine that runs a RoboRumble client. But I quite disagree with needing a quad core machine to run two Robocodes safely. On my MacBook Pro (Core 2 Duo, 2.8 GHz), I can run a second minimized Robocode with no slowdown to the first. Neither core even hits 100% utilization. That's not true of every dual core machine, so you should test it before trying it - my MacBook 2.0 GHz sees about a 15% slowdown in each if I run two at once. For RoboResearch, I'd certainly still run two threads and just adjust the CPU constant, but for the rumble, it's always better to be extra cautious. Keep in mind that Melee has a much better chance of spilling over into a second CPU core, as well.

On a separate note, another reason to have them separate is data saving. You don't really want bots learning from battles that you're watching and taking that knowledge into the RoboRumble. And some bots have configurable options in their data files, like Shadow can be set not to fire. You really don't want to be playing with that option and then leave him that way in the rumble.

--Voidious 20:10, 30 November 2009 (UTC)

Ok, new problem. With Windows7 - 64-bit, when trying to run 1.6.1.4 roborumble, I'm getting an array out of bounds exception as soon as it tries to run a battle. Any ideas? Also, wehn can we switch to the new version for rumbles? --Miked0801 04:15, 31 January 2010 (UTC)

Very odd issue... Is this an issue with any bot or just a specific one. As far as switching to a new version for the rumble, we can't yet. I've tested 1.7.1.6 and there are still pending rumble-relevant bugs. I intend to watch for 1.7.1.7 betas/alphas very closely so I can help ensure 1.7.1.7 will be rumble-ready. --Rednaxela 06:03, 31 January 2010 (UTC)

Appears not be be bot related. I also rolled back 64-bit java and just used 32-bit and still am getting the same issue:

Preparing battles list ... Using smart battles is true

Could it have something to do with multi-core or hyper-threading? I remember something about having to assign the Robocode process to a specific core/CPU on Windows, but I have no experience with it myself. That's the only thing I can think to try... Is it Robocode, too, or just RoboRumble? --Voidious 17:57, 31 January 2010 (UTC)

Just Rumble, and only this particular version - and yes, this is a 4 core system.

I believe that deleting the robot database file and letting it reconstitute the list has cleared up that problem for me in the past, many versions ago. I vaguely recall guessing it was related to a faulty bot download, but this was literally years ago. -- Martin Pedersen

I'll give this a shot tonight when I get home. If it works, I should be able to run 3 clients at once without hurting any other performance on system during the day. --Miked0801 19:31, 1 February 2010 (UTC)

I was toying around on the RR Rankings page and sorted by # Battles. Toorkild has over twice the number of battles as the next highest. Clearly some combination of the bot and Roborumble@Home is out of whack.

We're (finally) getting our internet sorted tomorrow so I should be able to start running more battles again soon. Is there any reason I shouldn't set BATTLESPERBOT to something higher to get some of the newer melee bots caught up a bit?

Surely you can set this variable as large as possible, since most bots already had way more battles than this value. And there could be a pull request to robocode to change the default settings.

That's what I figured but I didn't want to be the person who screwed up the results and forced them to be recalculated from scratch so figured I'd check with those who know better than I do. Looks to me like a default of 100k wouldn't be unreasonable for melee. Not sure about duels, maybe 30k?

I think the best is to dynamically adjsut the value based on current battles per bot, e.g. 80% * pct1 of battles per bot. In the meanwhile, you can safely set this value lower than the second lowest battle counts.

If I recall correctly, even if all bots have more than BATTLESPERBOT battles, bots with less battles get some priority. An other priority is 'old' battles (where f.e. the last battle is from 2020) even if those bots have a lot of battles. Also if I recall correctly, in melee there is some protection to prevent battles between only 'new' bots, I think only 1 new bot per battle and the rest quite randomly. Setting the BATTLESPERBOT higher does not influence this. Ofcourse bots with incomplete battles always get the highest priority.

Currently, the Robocode download site shows versions 1.9.2.6, 1.9.2.5, 1.9.0.0, 1.8.0.0, 1.7.4.4, 1.6.1.4, and 1.0.7. Versions 1.8.1.0 and 1.8.2.0 are not available. Also, the Roborumble Superpack link is now a dead link. Are there any other versions that are okay to use? If not, we may need to host the older suitable Robocode versions somewhere and update this page accordingly.

Hey, according to [1] the currently used version is 1.9.2.5. I can update to 1.9.2.6 if we need it.

Otherwise feel free to fix old links and reword pages, this is a wiki for a reason =)

Ah, I didn't know the version was reported there. I'll update the page that suggests older versions. Thanks.

The Superpack download link(to Dropbox) is broken, Dropbox says "File not Found 404", please update it.

Rednaxela setup this automatic mirror which includes a big zip of all the current RoboRumble participants: [1] ... We should probably replace the superpack link to just point to that.

Seeing as I was going to try this on a RP2 soon, I was going to get it working on my laptop first. But I had a couple of questions for those in the know that don't seem to be answered on the page or the discussion:

1) Should we always run the latest version of Robocode available for the rumble? (Starting with Rumble page mentions several versions of Robocode, none of which are the latest) 2) Does it matter any more what version of Java we use to run the Rumble with? 3) Does it matter if I interrupt the rumble process at any time? Will this corrupt the results? Or can I run a few battles, quit, start again etc etc.

Thanks! (I might turn the answers into an FAQ on the rumble page)

As an addendum to this, the same applies to the robots you submit to the RR. I see the latest Agent Smith has disappeared from the RR results but i'm not sure why but I was wondering if it was because I compiled it against the latest version of Robocode and Java but I'm not sure how I find out what the problem is! :)

1. Roborumble version allowed is here: [1] - currently 1.9.2.3
2. Anything Java6+ should be fine for running
3. Interrupt away! It will have to re-download some of the files on startup though, and will only upload results once it has been running for a while. And you only get priority battles when you upload results, so until then you might be running battles the server doesn't think is important.

Addendum: Try to compile with Java 6 (or 7) compatibility, since you don't know how old the JVM they are running on is. Also, it looks like it has been a few days since anybody has run battles, and until they do nothing will happen =)

Have fun!

I'm running battles right now

Can someone update this page with the correct URLs to get roborumble to work? Thanks.

Might also be good if someone puts a note on the page about Java versions. Lots of "Unsupported major.minor version 51.0" running with Java 1.6. I'm not sure what we should be using at this point.

I tried simply replacing darkcanuck.net with literumble.appspot.com, but apparently it's more complex than that. Roborumble can't download the ratings file and can't upload results.

That should be all you need, make sure you replace the URL for all 3 instances. The default Robocode install should come with the correct URLs now.

A couple of things. One, the URLs no longer have "/rumble/" like the used to. Removing that fixed the URLs. Also, it appears the accepted clients are now 1.8.1.0 and 1.8.2.0. It appears the 1.7.3.x clients are no longer accepted. I'll have to check, but the 1.8 Robocode clients may require Java 1.7. Guess I'll find out in the next few days. I'll try to update this page, but I am kind of learning as I go to figure it all out.

I updated the "From standard Robocode" section. Additional updates are required to bring the page up to date. Someone needs to bring all the superpack info up to date. I'm not personally up to date on what superpacks are available. If no one else updates it, I'll get it figured out in a few days and update it.

I'm sure the "major.minor" thing has come up before, but I didn't find it in a quick search. The list of robots I see this on includes: alpha.RainingFire ancientpyro.megas.kbot.KBot bots.UberBot bumblebee.Bumblebee cb.DeepThought cb.droid.Polyphem cb.Femto cb.mega.Enigma cb.micro.Haiduc cb.nano.Chasseur cb.Sabertooth cb.test.Provocateur com.timothyveletta.FuzzyBot daemons.DizzyA dhn.Immortal fromHell.C4H10O kb.PingPong kenran.InfiniteObscurity Lo_Ian.Gandalf_V4 mae.Mae1 mb.Beast mb.Monte qualidafial.MajorDick rc.RCBot romz.robot.circular.WildRabbit romz.robot.guessfactor.TeasingFox romz.robot.Test sfergus.Terminator stranger.nano.TestBot suh.micro.MirrorPM suh.micro.WallPM suh.nano.AntiGravityL suh.nano.CornerRL suh.nano.MyFirstAdvancedRobot suh.nano.RandomPM tkt.RedShift zignd.ZigIndexOutOfRange

Yikes! We're only supposed to require Java 6. And in the past I've removed bots from the rumble for requiring Java 7 and put a note on the participants page for those bots. But with that many, I wonder if it's time for us to just say to use Java 7?

At this point, I'd note that Java 6 is no longer being maintained for security fixes, and has outstanding exploits against it so... better be upgrading to Java 7 for other reasons.
