Yeah.  I had a list of issues on the runtime side.  The interpreter
was the big one as I recall.

It seems like it should work, but I admit I forgot to test it.  Sigh.
I've made a note and I'll write a test case (or a PR, at least) once I
clear my current list (i.e., it will be a while).

If you don't mind having your code potentially break (because you'll
be relying on libgcj internals), you can also follow the code sequence
the compiler uses: call _Jv_LookupInterfaceMethod and treat the result
as a function pointer.
