Client java version

Java 7 compatible is a very good idea, I am on 1.7_051 (but intend to go to JDK 8 in the near future) and can't run battles for a handful of bots. Just look at the missing pairings of GrubbmThree 0.9a. Btw, other clients should do those, why don't they. But it seems that there are also a few bots that can't handle a Java 8 client, like tcf.Drifter and sm.Devil (see comparison between GrubbmThree and MaxRisk)

There is something fishy with literumble. In console, I see a lot of entries like

Ignoring: gh.micro.GrubbmThree 0.9a,cb.nano.Insomnia 1.0,SERVER
Ignoring: gh.micro.GrubbmThree 0.9a,dsekercioglu.ColdBreath 1.9,SERVER

Nothing to do with MS products, just an indirect download link. Dropbox and Google Drive do this as well.

Direct download link: https://qevpmw.dm2304.livefilestore.com/y4mj6ooicv7LFLWmhTf1-ozrosL2kMwHPfHvkZe77l8RQ6WUHPgBUlU3jh5ty3cqIgmjMjT94WgbXlvk7Kf3Wqhuft-mcv8ZhBZ5t5mL662MRNHJfTuEqA9Kx1NPU3_vM9VA9-m6i_MMlswLF6cJZmpYzx0oqrP-YIXlpNzTVRleyRYH4wAA-rvVXwF53qExNPYeRPUfUcAlz51BGUEQfONaA/gh.micro.GrubbmThree_0.9a.jar?download&psid=1

That link broke too. (Apparently OneDrive direct download links are not permanent.) Luckily, Rednaxela's server picked it up.

I will look into that this evening, I switched provider, so my old webspace is gone. It explains why I provided most (or all) of the battles although I have separate installs for robocode and roborumble.

Put them (version a b c and d) on GoogleDrive now. Still missing 7 pairings, so I wait a bit before switching to 0.9b

According to the code, it shouldn't be harmful. It's just to make sure the client has the JAR, and to prevent duplicates.

// Check that competitors exist
String jar1 = items[0].replace(' ', '_') + ".jar";
boolean exists1 = (new File(botsrepository + jar1)).exists() && namesAll.contains(items[0]);
String jar2 = items[1].replace(' ', '_') + ".jar";
boolean exists2 = (new File(botsrepository + jar2)).exists() && namesAll.contains(items[1]);

// Add battles to priority battles list
if (exists1 && exists2 && !priorityBattles.contains(record)) {
    priorityBattles.add(record);
} else {
    System.out.println("Ignoring: " + record);
}
