WSDL Endpoints Stored in the Registry Cannot be Used
----------------------------------------------------

                 Key: SYNAPSE-577
                 URL: https://issues.apache.org/jira/browse/SYNAPSE-577
             Project: Synapse
          Issue Type: Bug
          Components: Core, Endpoints
    Affects Versions: NIGHTLY
         Environment: Any
            Reporter: Hiranya Jayathilaka
             Fix For: 1.3, NIGHTLY


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.
