Long live necro threads ... I know, sorry, but I really thought that might be interesting.
You see, in reality I don't see any big commercial game having to do anything with Java at all.
So I found this interesting thread on the Bohemia Interactive Studio (BIS) Forums: http://forums.bistudio.com/showthread.php?t=128800
It talks about a game "Take on Helicopters" by BIS (a helicopter simulator as close as it possibly gets to reality and still being a game which is fun) which will get JVM scripting support in one of it's future patches (the game itself was released last autumn).
So, "Take on Helicopters" isn't that interesting (at least IMHO), but "the other" game franchise by BIS is called "ARMA", a military game simulator. The ARMA series will reach is third installment end of this year (may also slip into next year) and a comment by one of the game developers in the above thread basically confirms it's for ARMA3 too: http://forums.bistudio.com/showthread.php?t=128800#3 .
BIS was long known for their scripting support in their games but used something home-baked called SQF and it was/is quite arcane to use.
So, I hope this post is interesting to other parties also ... cheers.
