I've spent a night scratching my head about the behavior of proxy-super in the presence of exceptions as well. I figured it was something like what you found, but by that point I just didn't trust proxy that much anymore and wrote that little bit in Java [1]. If I were a better person I would have hunted it down and filed a JIRA.
