State-Changed-Why:
    Hi.
    
    This isn't a bug.  gcj requires its own class library to operate properly.  Giving it the JDK 1.4 class library simply won't work.
    
    (Arguably it should work for `gcj -C', but that is not the bug you reported, and we already have a PR for that anyway.)
    
    In your example, gcj fails because it can't read the JDK 1.4 class file.  That too is a bug, and I believe it has already been fixed for 3.1.  However, even with that fix what you're trying to do won't work.
