java.lang.LinkageError: loader constraint violation in interface itable initialization

I have a working web service project using axis2 1.5.5 and rampart 1.6.0 deployed on JBoss. I tried to upgrade the axis2 and rampart versions to 1.6.2. When I use the 1.6.2 related jars and try to build the code, I got minor errors which I corrected (WSHandlerResult.getResults() now returns a List rather than a Vector which I was using before) and then tried to deploy this on JBoss. The service gets deployed but when I try to view the services (http://localhost:8080/axis2/) I get an error:
