Client java version

Can we have a quick survey about java version with which you run your litumble clients?

I see that performance of my bots dropped since I switched to java-8-openjdk for bot compilations. Plus I see ridiculosly low scores for my bot against some very simple bots at the literumble. On my machine I beat them with much bigger margin. So I suspect that there is something strange with one of the clients.

For the record, I compile everything with java-8-openjdk and run my literumble clients with java provided within this jdk.

    I'm using Java 8 for my rumbles. However, it seems that some bot stopped working on Java 8? etc. MoxieBot.

    I'm also using Java 8 and its features for bot development. However, I compile my bot with Java 8, then transpile the bytecode to Java 6 compatible using retrolambda, as Java 8 compiled code will generally refuse to run on lower platform.

      Cross porting from Java 8 seems to be excessive, if the rest of us are running Java 8. But let's see what others are running.

        But why risk getting low scores when there are someone using Java6? I think anyone who participant in rumble should make the bot compatible with Java 6 until it is not officially supported by the literumble.

        Maybe what we really need is a vote for moving the minimum requirement of running rumble from Java 6 to Java 8?

          The problem with the Robocode community is that everyone talks making changes, but no one actually does anything.

            By the way, ncj.MoxieBot 1.0 is running OK on my machine. It sometimes freezes but it seems to be the fault of the internal logic.

              But all my bots are getting 100% against MoxieBot on my computer, whereas there seems to be some 50% on the rumble, which makes me think that it doesn't work as expected on Java 8.

                        Java 1.7, as I just use an older unused computer for it. Some bots don't run in the rumble, but those battles are not even fought, so no pollution of the stats. I plan to update to Java 1.8 later this week.
