      Description

      FULL PRODUCT VERSION :
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_10-b03)
      Java HotSpot(TM) Client VM (build 1.5.0_10-b03, mixed mode, sharing)

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows XP [Version 5.1.2600]

      A DESCRIPTION OF THE PROBLEM :
      When one uses JFileChooser from an applet, leaves the applet page, returns to the applet page, and attempts to use JFileChooser again from the applet, the JPI deadlocks in JFileChooser in Windows Look and Feel code. [Note you must be using the Windows Look and Feel for the issue to occur.]

      This issue can be reproduced in both Internet Explorer and Firefox browsers with Java 5. Unfortunately, it is not reproducible on all Windows systems -- to the best of my knowledge all systems where the issue has been reproduced had 2 or more CPUs. I believe this issue is reproducible always or almost always on machines where it can be reproduced at all.

      We have not managed to reproduce this issue in Java 6 -- and I suspect from examining the threading changes there that this issue is not reproducible there. Unfortunately, we cannot require Java 6 as of yet and must have a resolution for this issue in Java 5. [I would, however, appreciate confirmation that the issue is not possible in Java 6.]

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Use JFileChooser from an applet, leaves the applet page, returns to the applet page, and attempts to use JFileChooser again from the applet. [Note you must be using the Windows Look and Feel for the issue to occur.]


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      JFileChooser should come up and the deadlock should certainly not occur.
      ACTUAL -
      A deadlock occurs. The following full thread dump clearly shows this:
