Public bug reported: I'm not sure if it's a java or gtk+ bug. I think the issue is with the gtkwrapper used by some java library (probably swig?).
When trying to execute some softwares it becomes unresponsible. Opening the System Monitor you can see that the process is sleeping and it has a subprocess gtkhelper, also sleeping. If you end or kill the gtkhelper process the software resumes it's execution normaly. It seems to happen only when a kind of pop-up is used. To reproduce this bug you can try to use the robocode jar from IBM v1.1.2 from here:[ http://sourceforge.net/project/showfiles.php?group_id=37202 ]. When you execute the jar (java -jar robocodexxx.jar) you'll se a disclaimer and then it goes out. try the steps above to resume the execution. ** Affects: Ubuntu Importance: Untriaged Status: Unconfirmed -- gtkhelper breaks java apps https://launchpad.net/bugs/57838 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
