I think this should be fixed everywhere.

I just tried this package with gcj, and the specfile needed a couple of
changes:

The problem with debuginfo isn't that gcj doesn't support Java 1.6, it's that
no debuginfo is being generated at all.

By the way, I don't understand this:

BuildRequires:    java-devel >= 1.7
Requires:         java >= 1.7

why 1.7 ?
