i get this when debugging my bot in non native mode

2-Jun-2008 1:19:43 AM ojvm.machine.ControlUnit makeAndThrow

Its not preventing my bot to behave correctly in any way, and im not getting any conversion (int to bool) error while in native.

I dont think its a serious error, but still i think you should look at it. This bot is the one i currently use so feel free to look if you do get the message too.

hey, i think i've seen this bug before too. i believe it's to do with the static initializers. try giving your booleans a default value to get rid of it like:

boolean b = false;

ah, lol, i think i figured where this "crash" come from, did you ever test the 100000 instruction limit ? my bot can easily go over this (about 3.5k instruction on one bot some time) it supposed to cycle thrue all bot bot so if they dont receive cycle in one tick, they should receive it in the next one. This is only a theory tho. Since well, vs the common ai, i cant get a game with enough bot before my ai win ><

hehe, i figured why my bot were "crashing" and about the error msg, it was indeed because a boolean wasnt initialised tho, it wasnt static, but its gone now. =D

the 100k instruction limit should be pretty well tested by now. a lot of bots run over this one =)

i'm probably going to switch the hackjvm to one more solid eventually...
