CXF Working on jboss EAP 6 - cxf

Question

Currently working on getting a CXF web service up and running on JBOSS EAP 6. I currently have it running and working for the most part but every time there is a verification issue I get the following error.
08:58:49,180 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/data-api].[CXFServlet]] (http-/0.0.0.0:8080-2) JBWEB000236: Servlet.service() for servlet CXFServlet threw exception: java.lang.NoSuchMethodError: javax.ws.rs.InternalServerErrorException.validate(Ljavax/ws/rs/core/Response;Ljavax/ws/rs/core/Response$Status;)Ljavax/ws/rs/core/Response;
I am assuming it is a version conflict but I have already excluded the JBoss jaxrs subsystem. Has anyone else had this issue?

This is the easiest solution to exclude JAX-RS API in your WAR only using jboss-deployment-structure.xml (without having to modify the Jboss standalone.xml):
exclude the module javaee.api completely
re-import the module javaee.api and exclude the JAX-RS classes
That's it!
Verified on Jboss EAP 6.2
jboss-deployment-structure.xml
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<deployment>
<dependencies>
<!-- Exclude JAX-RS: 2. re-import the javaee.api and exclude the JAX-RS classes -->
<module name="javaee.api" >
<imports>
<exclude path="javax/ws/**" />
</imports>
</module>
</dependencies>
<exclusions>
<!-- Exclude JAX-RS: 1. exclude the javaee.api completely -->
<module name="javaee.api" />
</exclusions>
</deployment>
</jboss-deployment-structure>
This brings the HTTP 500 without any stacktrace/NoSuchMethodExceptions to the invoker and clean Jackson Exceptions in the Jboss log file:
Caused by: com.fasterxml.jackson.databind.JsonMappingException: Can not deserialize instance of byte out of VALUE_STRING token
Also see this for the way to the solution.
In case you still have troubles with the Jboss-supplied JAX-RS subsystem (e.g. when trying to generate CXF Swagger-API I got a
java.lang.LinkageError: ClassCastException: attempting to castjar:file:/c:/jboss//modules/system/layers/base/javax/ws/rs/api/main/jboss-jaxrs-api_1.1_spec-1.0.1.Final-redhat-2.jar!/javax/ws/rs/ext/RuntimeDelegate.class to vfs:/c:/jboss/bin/content/myapp.war/WEB-INF/lib/javax.ws.rs-api-2.0.1.jar/javax/ws/rs/ext/RuntimeDelegate.class), then you can also exclude the whole jaxrs-subsystem:
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<deployment>
...
<exclude-subsystems>
<subsystem name="jaxrs" />
</exclude-subsystems>
</deployment>
</jboss-deployment-structure>
