It appears to use Java. So this may be a bug in a JRE.

Gezim, I guess you should open a bug against the package gij, and we'll be able to investigate more there. You've run into a very particular bug, and in Ubuntu the sound system is not so bad as you may think for desktop uses - actually it rocks, it's just that Java support may not be very well integrated to the rest of the system. Thanks for reporting anyway.
