A DESCRIPTION OF THE PROBLEM :
Native memory is leaked when many new MediaPlayer objects are created. It seems as though the memory leaks faster when the MediaPlayer is loading multiple files, opposed to a single file, however it still leaks if a single file is loaded into the MediaPlayer.

The Java heap is not leaking any memory.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the attached program for a period of time, you will start to notice the native memory of the application increase. Eventually, the application will crash, as it cannot get any more memory from the OS. On my system, it takes anywhere from 30 minutes for an hour until it runs out of memory, but the leak is noticeable within a few minutes of running the program.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Application does not crash and will continue to play indefinitely.
ACTUAL -
Application will eventually crash, as it has run out of system (not heap) memory.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
 Exception in thread "EventThread" java.lang.OutOfMemoryError: unable to create new native thread

REPRODUCIBILITY :
This bug can be reproduced always.
