The org.jboss.ejb3.client.ClientContainer currently uses a server side WebServiceRefHandler for processing service-ref metadata. It shouldn't use the server side handler, since the server side handler is even responsible for ENC injector creation, which shouldn't happen when running on the client side (via app client container).

The ClientContainer instead should use a client side service-ref handler which just creates field/method injectors for the service-ref metadata.
