Problems catching 401 faults

I'm specifying faults in my WADL like this:

          <fault status="401" mediaType="text/xml"
element="imom:webserviceFault">
            <doc>
              Bad credentials, you are not authorized to make this
              request.
            </doc>
          </fault>
          <fault status="404" mediaType="text/xml"
element="imom:webserviceFault">
            <doc>
              Fault if the radar cannot be found
            </doc>
          </fault>

In the generated code, I have no problems catching 404 faults. They do
indeed raise a WebserviceFaultException. However, when I generated a 401
fault by passing bad credentials I get a different exception:

  [java] Exception in thread "main" java.lang.IllegalArgumentException: is
parameter must not be null

I've confirmed that the server is generating a 401 fault code and that it
is sending an imom:webserviceFault element. This looks like a bug to me,
I guess I could go around it by catching an IllegalArgumentException and
treating it like a 401 error -- but this doesn't seem right.

Am I missing something?
