> We're getting the below NPE with CXF 2.1.3.
> It is related to CXF internal initialization.
> The problematic code is in ReflectionServiceFactoryBean in method
> protected boolean initializeClassInfo(OperationInfo o, Method method, List<String>
paramOrder) {
>    if (isWrapped(method)) {
>       if (o.getUnwrappedOperation() == null) {
>          //the "normal" algorithm didn't allow for unwrapping,
>          //but the annotations say unwrap this.   We'll need to
>          //make it.
>          WSDLServiceBuilder.checkForWrapped(o, true); // Inside of this code RULE no.2
fails and thus unwrapper operation isn't set at all
>       }
>       ...
>       o = o.getUnwrappedOperation(); // HERE the o variable is set to NULL
>    } else if (o.isUnwrappedCapable()) {
>       ...
>    }
>    o.setProperty(METHOD_PARAM_ANNOTATIONS, method.getParameterAnnotations()); // HERE
we're getting NPE because o was set to null
>    ...

> We're attaching also web service archive to reproduce the problem.
