did you try using the verbose option? do you have the WSDL available for us to look at?
Just found the issue should be related to the jira https://jira.jboss.org/jira/browse/JBWS-2687, it says that you guys will provide a "nocompile" option in command line, which version of SOA-P / EAP will contain this fix?
Depends on when the fix for that is ported to EAP branch. If you're allowed to, verify there's a JBPAPP jira issue for porting that immediately as soon as it's done upstream, otherwise create it.
If you're not allowed to just let me know.
