From JBoss EAP 7.1 Migration Guide:

"5.1.7. JAX-WS 2.2 Requirements for WebServiceRef
Containers must use JAX-WS 2.2 style constructors, using the WebServiceFeature class, to build clients that are injected into web service references. This means that user provided service classes injected by the container must implement JAX-WS 2.2 or later."

A new RHAMT Rule should be added to address this app migration issue, but description is not very specific to what is the concrete issue, thus no When and Perform provided.
