FULL PRODUCT VERSION :
java version "1.6.0_10-rc"
Java(TM) SE Runtime Environment (build 1.6.0_10-rc-b28)
Java HotSpot(TM) Client VM (build 11.0-b15, mixed mode, sharing)
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]
A DESCRIPTION OF THE PROBLEM :
If a JFileChooser is shown after a UI update just after rescanCurrentDirectory() is called, the EDT will sometimes lock up.
This report is identical to 6741372 except that in the sample code, everything is wrapped in a SwingUtilities.invokeLater(). Note that the The invokerLater() around dg.setVisible() (mentioned as strange in the evaluation for 6741372) is necessary to cause the lock-up for this particular example.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run code.
Hit "Show Dialog" button.
Close dialog.
Hit "Show Dialog" button again.
If that doesn't work:
Run code.
Hit "Show Dialog" button.
Resize dialog so it fills the screen.
Navigate to a directory with a lot of files in it.
Close dialog.
Hit "Show Dialog" button again.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expect the dialog to be shown each time the "Show DIalog" button is hit.
ACTUAL -
The application will sometimes lock up.

FYI, NetBeans users faced system locks with very similar thread dump. Maybe it's not exactly the same case, as "Swing-Shell" thread claims to be runnable, so it doesn't look like real deadlock, but according to users system really locks up. Please see thread dumps and more information at http://www.netbeans.org/issues/show_bug.cgi?id=132961 thank you.

FYI, NetBeans users faced system locks with very similar thread dump. Maybe it's not exactly the same case, as "Swing-Shell" thread claims to be runnable, so it doesn't look like real deadlock, but according to users system really locks up. Please see thread dumps and more information at http://www.netbeans.org/issues/show_bug.cgi?id=132961 thank you.
