WSDLGetInterceptor throws NullPointException when using EndpointSelectionInterceptor
------------------------------------------------------------------------------------

                 Key: CXF-3585
                 URL: https://issues.apache.org/jira/browse/CXF-3585
             Project: CXF
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.4
            Reporter: David Liu


Hi, 
  It looks like WSDLGetInterceptor assumes that the current exchange has one Endpoint, however,
there is the case we can use EndpointSelectionInterceptor to get the Endpoint later, so the
Endpoint could be null and which causes NullPointException .

e.g. WSDLGetInterceptor expects one Endpoint,
{code}
class WSDLGetInterceptor {
        //cannot have two wsdl's being written for the same endpoint at the same
        //time as the addresses may get mixed up
        synchronized (message.getExchange().getEndpoint()) {  <-- NullPointException 
 ...
{code}

However, the Endpoint is null at this moment and it will be set in EndpointSelectionInterceptor
later.
{code}
    public void handleMessage(Message message) throws Fault {
        Exchange ex = message.getExchange();
        Set<Endpoint> endpoints = CastUtils.cast((Set)ex.get(MultipleEndpointObserver.ENDPOINTS));

        Endpoint ep = selectEndpoint(message, endpoints);

        if (ep == null) {
            return;
        }

        ex.put(Endpoint.class, ep);
{code}
