OK, read POJO instead of MBean - advance to Go and start again...

fine - I now have code that can build a dynamic proxy and insert my POJO 
into the kernel using that. One problem - I need cglib 2.0.2. We are 
currently configured to run on 2.0 which does not have InterfaceMaker.

Should I start backporting InterfaceMaker to 2.0, or can we move up to 
2.0.2 or some version that has this class in it ?
