Yes, this has been fixed in openjdk-6 by now; sun-java6 is still broken
and I do not know about gcj.

We believe the problem is that libjasper-java upstream embeds a part of
eclipse's JDT compiler and it is used to resolve the dependencies. We
know Fedora does not suffer from this issue and they have the JDT
compiler embedded within their java-jasper.
  We are trying to make this work without having to embed the compiler;
unfortunately the interaction between eclipse and jasper is unlike any
other Java library interaction we seen so far, so it is taking us a
while to fix.
