That's a good point I wasn't even thinking about. Looking at the log Wompi posted again, I can see that all setup was completed on turn 0, and turn 0 wasn't skipped.

Voidious -- did you check to see if XanderCat appeared to be skipping a lot of turns on your Ubuntu/OJDK machine?

I can try to improve the CPU performance of my wave surfing drive and guess factor guns, and that might help, but it doesn't really explain the huge number of skipped turns on the first round. In the meantime, if skipped turns is a problem on Voidious' machine, I suppose for now I could just modify my bullet shielding system to try to account for skipped turns.

Remembered a 3rd possible cause of skipped turns. The JVM executes all code in interpreted mode for a while until JIT compiler kicks in. And at least in Sun/Oracle JVMs, the default JIT mode, client or server, varies with OS.

Hmm... frustratingly, XanderCat seems to have a higher success rate vs Virus (the most problematic on my system) when running through the UI. I did catch one 56% score with only 2 skipped turns, though, which raises some doubt that skipped turns are the issue (or only issue). Running some more single-threaded seasons with RoboRunner now, in case it's something like a fresh reboot helped (after testing in Windows earlier).

If you want to play around with it, I went ahead and released XanderCat 12.3. It's basically the same as 12.2 but I fixed some CPU performance issues. The main drives and guns execute quite a bit faster now with much lower peaks. Maybe it will make a difference...maybe not.
