and 1.1) versions though. The WorkflowServiceAdapterServiceStub is my service stub class.

> We were actually looking for the fix of Bug 1856  in 1.1.1 as our IBM Webservice WSDL
contains Abstract element, which is causing problems writing handlers on our service side
on the SOAP Request after deserialization. But now the client stopped creating SOAP Request
because of above NPE. I am not sure whether the Bug 1856 and above problem is related.
