Thomas Poetter commented on AXIS2-3892:
---------------------------------------
As an attempt of a workaround for the example in the last comment, I avoided
throwing an exception "Property cannot be null" in
InterActiveWebClientRampart.AccountInformationServiceStub and continued with
execution. This leads to the following error dump:

> WebServiceStub crashes with NullPointerException when web service function is

>
> Key: AXIS2-3892
> URL: https://issues.apache.org/jira/browse/AXIS2-3892
> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: codegen
> Affects Versions: 1.4
> Environment: WinXP for AXIS client + server, Rampart 1.4
> Reporter: Thomas Poetter
> Assignee: Amila Chinthaka Suriarachchi
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Call:
> InterActiveResponse result = stub.GetInfo(null);
> Crash in:
> public InterActiveResponse GetInfo(InterActiveRequest interActiveRequest0)
> env =
> toEnvelope(getFactory(_operationClient.getOptions().getSoapVersionURI()),
> interActiveRequest0, // <-- value of interActiveRequest0: null =>
> causes NullPointerException
> optimizeContent(new
> javax.xml.namespace.QName("https://xxx/AccountInformation";, "GetInfo")));
> I know that one fix is to prevent the client to call the service with null as
> argument. However, I feel the client shouldn't crash in this case but return
> null without crashing or throw an IllegalArgumentException or a similar -
> less fatal and more meaningful exception than NullPointerException.
