The issue is likely related to WildFly and that it has its 
classloader/classpath leaking on the xwiki webapp… So there’s probably a 
conflicting library version for the JAR that contains javax/ws/rs/core/Response.

See http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationJBoss and 
especially the line that says:

"       • If you have class loader issues read how JBoss AS7 Classloader works”

I don’t have the exact answer but I hope this will lead you to the right track.

Thanks
