PIT: Frames are not iconifying on XToolkit

Frames are not getting iconified when clicking the iconify button on the top right corner. They are not iconifying even when calling setExtendedState(Frame.ICONIFY). Looks like they momentarily iconify and gets restored.

This is happening on the following PIT build on all unix platforms with XToolkit. Not reproducible on Mustang - b35.

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-df153228_06_May_2005_08_56-b00)
Java HotSpot(TM) Client VM (build 1.6.0-ea-b35, mixed mode)

I am able to reproduce this on SolarisSparc9-CDE, Cinnabar, Linux AS 3.1 using the above PIT build. This is a basic feature and should work fine.
 
Run the attached test on any of the unix platforms mentioned above. Click on the button or the iconify button on the top-right corner. If the frame does not get iconified, the bug is reproduced.

The bug can be also reproduced by shading the frame or switching to another desktop (if supported by WM).
