-----------------------------------------------------------------

The null pointer exception will happen if the Endpoint is not initialized.
Added a check if the WSDLEndpoint is initiliazed before calling the onSuccess method in the
EndpointContext.
Let me know your comments.

> 1. Define a valid registry provider in the Synapse configuration
> 2. Store a WSDL endpoint definition in the registry
> 3. Create a proxy service which refers to the WSDL endpoint in the registry
> 4. Start Synapse and send a message to the proxy service
> Message will be dispatched to the back end service, but Synapse will fail to route the
response back. The following NPE occurs.

> This is because the endpoint returned by the AbstractRegistry is not initialized and
hence does not have an associated EndpointContext.
