Open File Dialog. You would see a text field - 'Enter full path or filename'. Right next to it, you would see a button. On clicking it the drop-down would appear. Keep the focus on this button and try pressing UP and DOWN arrow keys. The selection in the textfield will not change on the PIT build. Try pressing 'ESC'. The file dialog will not be disposed.

This is reproducible only on the given PIT build with XToolkit. Not reproducible on Mustang-b32.
I reproduced it on SolarisSparc9-CDE.

Here is the PIT build:
java version "1.6.0-awt.pit-int-awt-blade"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.6.0-awt.pit-int-awt-blade-dm97671_19_apr_2005_08_10)
Java HotSpot(TM) Client VM (build 1.6.0-ea-b32, mixed mode)

Run the attached test on Solaris/Linux. You would see a frame with a button. Click on the button. A file dialog would come up. Make sure focus is in the 'Enter path or full name' text field. Press TAB. Focus will be shifted to the button next to the textfield. Try pressing UP, DOWN, ESC keys. If nothing happens, the bug is reproduced.
