A DESCRIPTION OF THE PROBLEM :
This bug is hard to reproduce. It happened with our swing based application when started using webstart with activated java console window.

After startup of our application we opened a few windows and a modal dialog. Then we left the pc untouched for an hour.

After this time the application was not responding.

I found no bug report for this deadlock, but I found http://stackoverflow.com/questions/16818863/multiple-event-dispatch-threads-causing-deadlock-in-java-web-start-app
