      Above stacks were taken from inside eclipse debug.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      It seems to be happening more often if I visited a directory with a lot of folders/files once. Close it and try to reopen it again.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Deadlock inside swing's thread is bad, especially all we're doing is to bring up the JFileChooser.

      Looks like the Swing-shell is locking a Vector object (id=49) triggered by a FutureTask.
      ACTUAL -
      It shouldn't deadlock!

      REPRODUCIBILITY :
      This bug can be reproduced always.
