Today when testing dying with dignity, we simply throw an OutOfMemoryError. We know this should not get caught by any intermediate code and end up in the uncaught exception handler. This allows us to test that this exception handler is able to successfully kill the VM. However, it is on the table to no longer use the uncaught exception handler, but instead the built-in support for ExitOnOutOfMemoryError. A fake OutOfMemoryError would not be processed by this handler, so to prepare the way, we switch to using a real OutOfMemoryError.

This leaks jvm implementation into our tests. I am not really against that, but perhaps we can add a comment to remove the text from matching if it fails?
