Out of Memory Enhancement

Found this error when ran the game for about 15 minutes straight on Mac OS X. Full stack trace was:

Audio code in SoundHandler was creating a thread for every single sound that needed to be played, and then letting the threads hang around after finishing playing. Solution was to kill threads with Clip method close() after listening for event indicating the sound is finished playing.

However, solution is sloppy looking. Is there an easier way to stop the threads after a clip is finished playing its audio? Something involving a Thread join()?
