I am running the attached test on JDK7-b02 and I am getting a NPE when pressing CTRL+C on the console. This test basically creates a Frame for each GraphicsConfig available on the GraphicsDevice and renders some 2D graphics on to a canvas added to each of the frames.

This exception is not reproducible on JDK6-FCS and JDK7-b01 whereas it is reproducible on JDK7-b02. Also repoducible on JDK7-b10 AWT PIT build. This is specific to win32 and not reproducible on SolSparc10. I am filing it against AWT since AWT integrated into b02 and 2D did not.

Here is the exception-

I have attached a test - ScreenStandaloneTest.java. Compile and run it. When all the frames are loaded (around 26 on my machine), press CTRL+C on the console. you will get the above exception.
