> Project: Axis2
> Issue Type: Bug
> Reporter: Rich Scheuerle
> Assignee: Rich Scheuerle
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> The following NullPointerException may occur when invoking a JAX-WS async
> method
> java.lang.NullPointerException
> at
> org.apache.axis2.jaxws.marshaller.factory.MethodMarshallerFactory.
> getMarshaller(MethodMarshallerFactory.java:106) at
> org.apache.axis2.jaxws.client.proxy.JAXWSProxyHandler.
> getFaultResponse(JAXWSProxyHandler.java:473) at
> org.apache.axis2.jaxws.client.proxy.ProxyAsyncListener.
> getFaultResponse(ProxyAsyncListener.java:70) at
> org.apache.axis2.jaxws.client.async.AsyncResponse.
> processFaultResponse(AsyncResponse.java:431) at
> org.apache.axis2.jaxws.client.async.AsyncResponse.onError
> (AsyncResponse.java:129)
> ...
> 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.
