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.
