When I attempt to consume a webservice running on JBoss 4.0.2, it returns the following error

Searching around, it seems to be an issue with JAX-WS.  Here are a couple of bug reports that support this conclusion

http://java.net/jira/browse/JAX_WS-793

http://java.net/jira/browse/WSIT-285

Is there a workaround to this issue with JBoss, or does it require a different version of JAX-WS? I am not familiar at all with JBoss, so I don't know if I could just swap out the JAR with a newer version.
