Samuel, I'm planning to work on this soon. I don't know if your available time is a short term thing, but if it's not, would you consider putting this package under the maintainership of Debian Java Maintainers? That way future updates could be picked up by members of that team. If you don't want to do that, it's fine and I'll attach a patch to this bug.
