Java XPCOM on OS X cpu maxing out

Hi All,

I've followed the example found here: "http://developer.mozilla.org/en/
docs/
JavaXPCOM:Embedding_Mozilla_in_a_Java_Application_using_JavaXPCOM" (the
second example, with the window watcher) and am having a problem...

The application runs and blocks as expected at the appStartup.run();
line but nothing else happens. My CPU maxes out and I have to kill the
process before my macbook melts :)

Anyone else had this problem? I will try later on a linux box and see
if it is an OS X thing but was hoping someone could help me out on the
Mac.

Thanks
