Signals that a thread should terminate. This error is thrown in a thread when the Thread.stop() method is called for that thread. This is an unusual Error type that simply causes a thread to be terminated, but does not print an error message or cause the interpreter to exit. You may catch ThreadDeath errors to do any necessary cleanup for a thread, but if you do, you must re-throw the error, so that the thread actually terminates.
