Endpoint metrics do not work

When we consume an EJB 3 web service deployed at jbossws-cxf-3.1.1, its registered service endpoint metrics counters (RequestCount, ResponseCount... shown at http://127.0.0.1:8080/jbossws/services) not work: never increment values and always show cero.

Same happens with a POJO JSR-181 web service endpoint. Its registered service endpoint metrics counters (RequestCount, ResponseCount... shown at http://127.0.0.1:8080/jbossws/services) not work: never increment values and always show cero.

But the same web service deployed with jbossws-native, its registered service endpoint metrics counters work fine.
