The Jikes developer discussion list recently had a small thread about
this and at least according to my understanding they think the
specification is incomplete such that it cannot be implemented
correctly by a compiler to exactly match Sun's compiler.  Therefore
when Classpath is compiled with Jikes it is incompatible with any Sun
VM.  I wish Eric Blake could comment further to explain to us a bit
more if I've misrepresented in some way.
