> JAX-WS Provider Endpoints are supposed to be able to return 'null' to indicate that it's a one way MEP and no response is needed.  Web services ported from the Metro stack will fail on the Native stack if they use this feature because the Native stack seems to be expecting a non-null value to be returned at all times.  The API clearly states that null can be returned from invoke() to indicate a one way MEP when no response is required:
> https://jax-ws.dev.java.net/nonav/jax-ws-20-pfd/api/javax/xml/ws/Provider.html#invoke(T)
> On the native stack, when trying to return null from a Provider<SOAPMessage> invoke() operation, a NullPointerException is thrown:
