Jesse, related to your changes for issue 179597.
Comment 3 Jesse Glick 2011-04-07 13:45:53 UTC 
Not a real bug as such; it means the event queue was frozen due to some real performance issue, the user attempted to contact the IDE via command line, and got no response. The Thread.stop attempts to restart the event queue so you can recover. Not sure why it is popping up in the exception reporter; that just needs to be disabled somehow.

Not sure why this was made a P2. There was only a single report from 7.1 so far, and only a handful from 7.0.x.

Looks like a ThreadDeath somewhere inside WeakListenerImpl$ProxyListener.invoke is being rethrown as an InvocationTargetException; surprisingly, Method.invoke seems to wrap everything in an ITE, not just checked exceptions.
