Timothy Bish created ARTEMIS-1069:
-------------------------------------

             Summary: AMQP: Thread unsafe proton usage found
                 Key: ARTEMIS-1069
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-1069
             Project: ActiveMQ Artemis
          Issue Type: Bug
          Components: AMQP
    Affects Versions: 2.0.0
            Reporter: Timothy Bish
             Fix For: 2.next


Found a few cases in the AMQP handlers where proton objects are used outside the connection lock where the usage can cause updates to the Transport work list which if happens concurrently can break the state of the work list.  

Also found one case where a the code if offering credit to a sender which is not necessary as the sender credit is determined by the remote receiver flowing credit to it.
