I am right clicking inside a component and a popup menu is shown. clicking on one of the sub-menus and the respective menuitems appear. When I press 'ESC' the sub menu disappear. When I press 'ESC' again, I expect the popup menu to disappear but I am getting a NPE given below on the PIT build:

java.lang.NullPointerException

This is noticed only on the following PIT build and not reproducible on Mustang-b35. Hence this is a PIT failure. Reproducible only on XToolkit with 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-df153228_06_May_2005_08_56-b00)
Java HotSpot(TM) Client VM (build 1.6.0-ea-b35, mixed mode)

I have attached a sample test. Run it on XToolkit. Right click inside the choice component. You would see a popup menu. Click on one of the sub-menus. Press 'ESC' twice. If you get the above exception on the console, the bug is reproduced.
