This problems are thrown cause of different version of Resteasy Client implementation between your app and Jboss EAP modules. You are using the newest version of jaxrs-client, but JBoss EAP 6.3.0 use very old version (resteasy-jaxrs-2.3.8.Final-redhat-3).

Just download latest pack of JBoss Resteasy implementation (sometking like this: resteasy-jboss-modules-3.0.9.Final.zip) and unzip into EAP Modules folder replacing existing files modules.xml and adding new jars. Remeber replace all JARS from the ZIP (not only resteasy-jaxrs).
