How to run a standalone JAX-WS thin client in JBoss EAP 6

Issue

• I am using following four jar files to run the JAX-WS thin client: jboss-modules.jar, jaxb-impl-2.2.5-redhat-1.jar, jboss-jaxb-api_2.2_spec-1.0.4.Final-redhat-1.jar, istack-commons-runtime-2.6.1-redhat-1.jar
• Those four jars were enough to run a regular client. However I am getting the following exception when the code is involved to build a soap fault on the client side:

Caused by: java.lang.ClassCastException: com.sun.xml.bind.v2.runtime.JAXBContextImpl cannot be cast to com.sun.xml.internal.bind.api.JAXBRIContext
    at com.sun.xml.internal.ws.fault.SOAPFaultBuilder.<clinit>(SOAPFaultBuilder.java:550)
