ADDITIONAL SYSTEM INFORMATION :
standard win7 system

A DESCRIPTION OF THE PROBLEM :
The old workaround does not work on mp3 files. I have to completely shut the application down in order to delete or change a file.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
just load a few mp3 files sometimes the first one can be deleted but all others not.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
windows says Java has still this file opened.

---------- BEGIN SOURCE ----------
Media media = new Media("file path");
MediaPlayer mp = new MediaPlayer(media);
mp.play();
mp.stop();
mp.dispose();// does not work all time
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Didn't find one.

FREQUENCY : always
