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.
