What are robust one-way webservices, and how do I enable them in JBoss EAP 6?

Issue

I have a simple oneway webservice which takes single int param. I've marked the ws with @RolesAllowed("dev") and @SecurityDomain("other") annotations. I didn't setup any users in JBoss, so during the call from SoapUI, an exception is logged:

javax.ejb.EJBAccessException: JBAS014502: Invocation on method: public void com.redhat.testapp.OneWayServerEndpoint.testMethod(int) 
                                                       of bean: OneWayServerEndpoint is not allowed

But still the client gets HTTP 202. Since this causes us troubles, I had to study oneway webservices and I found out that this is actually a correct behavior. Is there any way to make JBoss/CXF return a different HTTP status if there was a problem processing the request?
