Recently I've been craving some game programming. I primarily use Linux, and was wondering if there are any good graphics libraries for Java development on Linux? Google didn't turn up very much useful information on the subject.
Also, would another language be better? I would like to avoid using python -- Ruby and Java are my two favorite languages. There doesn't seem to be much talk about game programming on Linux in general, unfortunately.
Any suggestions/resources? Easy portability or cross-platform functionality would be awesome too.
Oh, and I prefer 2D graphics.
