JavaSoundAudioClip stop() Method sequencer.addMetaEventListener(this); wrong?

FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
I think that the implementation in the class JavaSoundAudioClip in method stop() with the call
sequencer.addMetaEventListener(this);
was wrong.
It must be instead a call to
sequencer.removeMetaEventListener(this);


REPRODUCIBILITY :
This bug can be reproduced always.
