-Wall is supported.  It just doesn't do what you think.

Use -Wunused.  This is apparently a general gcc option.  It works with
gcj (but, unfortunately, on your example it prints too much -- a
lurking gcj bug).

I agree that gcj should enable -Wunused when -Wall is given, because
that is similar to what the C compiler does.  I consider this a bug in
gcj.  I'll submit a patch.
