[jira] [Created] (AMQ-6642) MessageStore update message can encounter NPE with KahaDB

Christopher L. Shannon created AMQ-6642:
-------------------------------------------

             Summary: MessageStore update message can encounter NPE with KahaDB
                 Key: AMQ-6642
                 URL: https://issues.apache.org/jira/browse/AMQ-6642
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.14.4
            Reporter: Christopher L. Shannon
            Assignee: Christopher L. Shannon
             Fix For: 5.15.0, 5.14.5


If KahaDB subscription statistics have been enabled (off by default) then it's possible to get a null pointer exception if updateMessage() is called on the message store.  This occurs if the destination is a Queue as there is not a proper null pointer check done for ackPositions which only exists when using a Topic.
