Rio,
These are CDI interceptors, not EJB interceptors. CDI interceptors work on POJOs and EJBs. I would have expected CDI to have seen the JAX-WS impl as a POJO and setup the interceptors accordingly.
Are you able to comment on my pull request? Two Weld guys (Ales Justin and Stuart Douglas) think this should work.

Thanks,
