HTTP transport sends zero length lists of polled callbacks
----------------------------------------------------------

                 Key: JBMESSAGING-818
                 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-818
             Project: JBoss Messaging
          Issue Type: Bug
    Affects Versions: 1.2.0.Beta2
            Reporter: Tim Fox
         Assigned To: Ron Sigal
             Fix For: 1.2.0.CR1


I have noticed that, at times, with the HTTP transport, the wireformat receives a list of polled callbacks of length zero.

This results in a pointless callback delivery being made from the server to the client.

This can be easily seen by adding the following logging to JMSWireformat:

    else if (param instanceof List)
            {
               // List of polled Callbacks, this is how messages are delivered when using
               // polled callbacks e.g. the HTTP transport
               
               //Sanity check
               if (((List)param).isEmpty())
               {
                  log.error("Got a polled callback list - but it is empty!!!");
               }

And then running the test suite. I notice most of these when running the crash tests.
