The only problem that reinstalling VASSAL will ever solve is if some
of VASSAL's files are corrupted. If that happens, you probably won't
be able to start VASSAL. Therefore: If you can start VASSAL,
reinstalling is unlikely to solve your problem. I wish we could convey
to everyone that reinstalling VASSAL is a waste of time except in very
specific circumstances.

Your particular problem is caused by a change in behavior from Java 6
to Java 7. I haven't had time yet to look into whether it's a
documented change in behavior or if VASSAL was relying on undocumented
behavior in Java 6---in which case the problem is ours---or whether we
are relying on unchanged, documented behavior, in which case it is a
bug in Java 7.

For the time being, if you want this to work properly, use Java 6.
