Hi,

Please consider switching to jax-rs. Perhaps seeing the other cxf jax-rs pioneers struggling to make things working with our JAX-RS 
being involved is not very encouraging :-), it's still a better move. We'll get the JAX-RS issues sorted out eventually and I reckon 
that the inhertitance is supported quite well in our JAX-RS impl...

Cheers, Sergey
