Yep this package is an absolute requirement of CMP 2.0. The
java.lang.reflect.Proxy package can't generate a subclass of an abstract
class, and this is where BCEL could take over.
If you want to look into writing a replacement with BCEL that would be
very cool (they do have a sample dynamic proxy generator).
