This is more of a philosophical issue than a technical one.

My take on it is:

Where both gcj and the JDK conform to the spec, but behave
differently, we change gcj to match the JDK.

Where the JDK doesn't conform to the spec, but gcj does, we leave gcj
well alone.

This might be problematic where some applications rely on incorrect
behaviour.  When that happens, we have to make our decision on a
case-by-case basis.
