I am attaching a simple applet which uses some basic swing components specifically JMenu crashes when you invoke the last menu item ( a pop-up menu).

To reproduce unzip the attached file and compile the Java source files. Then run TestApplet.htm in IE and click on File->other options.

The following stack trace is provided
