> The problem occurs because the JAX-WS runtime must find and inspect the JAX-WS synchronous
method in some cases.
> For example, the synchronous method contains the checked exceptions and must be examined
when the web service
> returns a fault.
> If the synchronous method has a name that is different than the wsdl operation name,
the search may fail.
> This triggers the NullPointerException.
> Proposed Solutoin:
> I have a small change to the search algorithm which will guarantee that the synchronous
method is found.
> Kudos to Paul Mariduena for providing a test and testing this fix.
> I will be committing the change later today.
