Got a reproducer for you: added AudioClip to the Monkey Tester
https://github.com/andy-goryachev-oracle/MonkeyTest

Build a jar and run it.  Select AudioClip page, then pressing "Play XX" button would play .wav or .mp3 file from the said jar.

What I see is that while the .wav file is being played correctly, the .mp3 does not play (no audio).

The bad news is that if I randomly press these buttons, it crashes
