Note, this is probably two issues. While NullAI works for me with the passed JAVA_HOME env var, ZKGBAI still hangs (like in mojjj's windows case?)

first you should fix these errors before continuing:

i suggest to delete /home/mo6ba4/.spring/AI/. The AI's / Interfaces basicly aren't compatible to different versions of spring. Maybe in some cases it works, mostly it doesn't work.

second: how many memory is available at your system?
java can be bitchy when to few continous memory is available, i.e. enabling swap memory (when it disabled) could fix the issue.


third: possible this is caused by using java 8, maybe works with java 7?! didn't try for a long while, maybe ask in form, an Java AI dev with the knowledge can respond.

hm, maybe a duplicate of 0004565 :-|

thx for the resposnses

1) done. started a game vs zkgb with no change. freeze at start

2) i got 16G ram and 8G swap. ram is not full when playing zk.

3) TODO

meh, i can at least reproduce the error, zk crashes for me, too. in ba it seems to work.

when run with gdb it hangs here:

basicly CCustomExplosionGenerator::ParseExplosionCode

(wtf? memory corruption?)

fun fact:

adding "return 0" in front of:

int LuaSyncedCtrl::SpawnCEG(lua_State* L)

makes it work for me!

just a wild guess:

jvm changes a lot of the running process: i.e. signal handlers are changed


also the CEG related warnings (Warning: [CCEG::Load]...) should be fixed before this is investigated more


i spent already a lot of time with fsanitize=address build which just crashes with no informal message. gdb always showed the above error and sometimes it randomly crashed before

Interesting enough i can't reproduce it with arch64 + springlobby + spring on gcc6.2.1 (new ABI) + /usr/lib/jvm/java-8-openjdk/jre + zkgb, nullJavaAI, nullOOJavAI.
Everything works.

I tested with the official build (on a x64 16.04 ubuntu) and with a debug build with gcc 5.4.0. Both of these failed, so not sure whats the cause. The official build uses the old abi and gcc 5.4 should have used the new abi: imo this shouldn't matter as the jvm is written in C.

still interesting that it works, maybe someone finds the real cause of the problem.

If i remember right i used oracle jre, too. So this could be the issue here, will test soon.

the official build is compiled with oracle jdk:

"oracle-jdk-bin-1.7.0.13"
