Lambdas and 1.9.2.5

1.9.2.5 has a known bug with lambdas which has already been fixed in 1.9.2.6

currently 1.9.2.5 is the only accepted roborumble and it gets

   Got an error with e32.Omni: java.lang.ClassNotFoundException

You could use retrolambda to transpile lambdas as I do, or just avoid using lambdas until 1.9.2.6+ is accepted.

Ah, thanks for the heads up. I haven't explicitly used lambdas to my knowledge (though I'll check this weekend), but method references instead. I'm guessing those also cause this behavior.

Yes, method references and lambdas are the same thing in JVM

Oops, it seems that roborumble client cannot download your bot, from all over the world. Maybe dropbox set the restriction, or there may be some bug in any of the ends.

And after downloading your bot manually, roborumble client throws exception and exits completely.

Btw, can you try running your bot with robocode 1.9.2.5? And can you try running roborumble to see whether it can download your bot automatically or not?
