Marshaller to stop before Transport to avoid NullPointerException
-----------------------------------------------------------------

                 Key: ISPN-574
                 URL: https://jira.jboss.org/browse/ISPN-574
             Project: Infinispan
          Issue Type: Bug
          Components: Marshalling, RPC
    Affects Versions: 4.1.0.CR2, 4.0.0.Final
            Reporter: Galder Zamarreno
            Assignee: Galder Zamarreno
             Fix For: 4.1.0.Final


Currently both the marshaller and transport have the same stop priority.

Marshaller should stop *after* transport, otherwise the marshaller could have been stopped but something might still be received in the transport channel and you could get an NPE like this:
