This one was my fault.  In my C++ wrapper class for Classification, I
had a forward declaration for the jblocks.security.Classification class,
but I had neglected to wrap it in an extern "Java" block.  After fixing
that and running my test again, your suggestion of placing an abstract
declaration in the Java file for the unimplemented interface method
worked like a charm.

Thanks so much for your help!
