Repeatedly creating/destroying windows under NT crashes JVM

The following class will bring up a panel with a button, clicking the button will close the window and repeat the process. When this is run on NT if you repeatedly click on the button eventually you get an error where an instruction is trying to reference memory at 0x10, which could not be written, thus killing the program. I was not able to get this to happen under Solaris, only on NT. While this example may seem contrived it is taken from a much larger program where it crashes quite regularly.
