Run swingset 2 demo.Go to JFileChooser demo
Open any of the file chooser
Now try to go into the directories , change the top menu, change the File Format. By doing that it can be seen that sometimes it takes longer to update the files list.
But resizing the files list gets updated.
This issue is not reproducible every-time.

Screenshot is attached.
In one screenshot the files list in not there and it appears by resizing in the another screenshot.
