TUSCANY-3641 - start adding a processor to handle JAXWS annotations in implementation.java classes. I'm a little surprised that this isn't already handled so I'm committing this as a demonstration of intent with a view to asking on the ML is this function is achieved in some way I'm not yet aware of.
