|0005952||Spring engine||AI||public||2018-04-04 21:29||2019-10-14 22:07|
|Product Version||104.0 +git|
|Target Version||Fixed in Version|
|Summary||0005952: Java AIs are not killed on Spring.Reload|
|Description||When playing multiple games in a row, Java AIs start colonizing spring's JVM memory. It's possible to reduce the impact by releasing as much memory as possible in the AI once the game is over. It would be best to kill the AI completely though.|
|Steps To Reproduce||Play a game with a java AI. |
Restart the game.
The new game has two AIs in the JVM, the old one simply doesn't receive any call-ins anymore.
|Tags||No tags attached.|
|Checked infolog.txt for lua Errors|
atm this is by design:
existing env is not reused:
existing env is not freed:

I remember there being some sort (forgot the details) of issue with sending release events to Java AI's, which was apparently "solved" by making java_skirmishAI_release a no-op.
the Java bridge code also long predates Spring.Reload so envs not being freed wasn't a real problem until that became available and reliable.
Maybe that's why implementing release() didn't do anything to fix the problem. :P
I can confirm that the AI almost always fails to load by the third game in using default JRE settings. A failure to free the memory from previously instantiated AIs could probably cause that.
I'm not sure if spring crashing on shutdown is related or not, but there was at one time a correlation with java AIs and cpp AIs and crashing when running both in the same game. I'll have to test that later and maybe make a separate issue for it.
|with spring.reload this makes java ais IMHO unusable -> major|
