Reconfirmed in Ubuntu Quantal - adding ftbfs tag.

I haven't looked at the entire log or anything, but I suspect it is because upstream is using a special source/target combination that allows them to compile 1.5+ code into 1.4 byte code (or so). I believe it is JSR14...

To my knowledge, upstream is already aware of it[1], though I am not quite up to speed with its status. As far as I can tell, it is currently targeted for the release after 3.8 (3.9 or possible 4.X).
