Ok. I think overall the changes look good. I'd still like to see a test. Also, I'd like to see the jdb output after the fix. Maybe include the `list` output when jdb stops for the exception. It looks like jdb will print the name of the exception object and also the location where it will be caught, and I assume `list` will show you where it was thrown (although I think if this info is wrong in the ExceptionEvent, a jdb user would not notice so jdb it instead getting it from the current Thread info).
