How to propagate SecurityContext through ESB message, while invoking ESB service externally through ServiceInvoker ?

Issue

• I have an ESB service WebServiceInvoke through which I am invoking a JBossWS webservice through SOAPProcessor action. In the web service implementation I have access to the logged in user which indicates that the Security Context has been propagated to the WebService.
  In the webservice I create a new ESB Message like below, and with the help of ServiceInvoker I call the target ESB Service TargetServiceESB.

Message msg = MessageFactory.getInstance().getMessage();
ServiceInvoker invoker = new ServiceInvoker(myServiceCategory, myServiceName);
response = invoker.deliverSync(msg, 2000);

But, to my surprise the SecurityContext is not propagated from the webservice implementation to the ESB Service. Can you please suggest me if
I have to manually set the security context on the ESB Message as shown below?

msg.getContext.setContext(SecurityService.AUTH_REQUEST, encrypted);
