Deadlock between AWTEventQueue of Application and Webstart-Console

    Details

      Description

      FULL PRODUCT VERSION :
      java version " 1.7.0_25 "
      Java(TM) SE Runtime Environment (build 1.7.0_25-b16)
      Java HotSpot(TM) Client VM (build 23.25-b01, mixed mode, sharing)

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows
      Version 6.1 (Build 7601: Service Pack 1)

      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
