State-Changed-Why:
    Thanks.  I was able to reproduce this problem with the trunk cvs gcj.
    I've checked in the fix.  It will appear in gcj 3.1.  
    Unfortunately it is too late for 3.0.3.
    If you try the trunk version and you still have problems,
    tell me and I will reopen the PR.

Gcj is actually from Debian package version 2:3.0.3-1,
so this might be a gcj 3.0.3 with a bogus version report
>Description:

I include a single .class file, generated by the Nice compiler.
This bug is link to loading a class field
that has a ConstantValue attribute.
Java runs fine on this class, but if compiled with gcj,
the generated program throws a NullPointer.
