    Description

      Testing the Broker against Rhea's example/helloworld.js shows that the AMQP 1.0 protocol layer fails in at least two places.

      The first is if the Target (not mandatory) is omitted from the incoming attach.

      -Default source and target to empty objects appears to resolve the problem.-
      The protocol tests should be strengthen to cover these cases.

      (updated: 2017-10-24 - renamed JIRA title following discussions below to more accurately capture the problem)
