Seems to be a problem in the bug handler. I believe it is trying to log a Vassal version mismatch.

Take any module, edit the buildfile and bump the version number up to 3.2.0. It’s guaranteed to fail - ErrorDialog.warning():277 passes null as the thrown which is used to print a Stacktrace in ErrorLog.log().
