Subject [jira] [Created] (QPID-8432) [Broker-J][7.0.x] Message references can be leaked in some rare circumstances
Date Fri, 03 Apr 2020 10:13:00 GMT
Alex Rudyy created QPID-8432:

             Summary: [Broker-J][7.0.x] Message references can be leaked in some rare circumstances
                 Key: QPID-8432
                 URL: https://issues.apache.org/jira/browse/QPID-8432
             Project: Qpid
          Issue Type: Bug
          Components: Broker-J
    Affects Versions: qpid-java-broker-7.1.1, qpid-java-broker-7.1.2, qpid-java-broker-7.1.3,
qpid-java-broker-7.1.4, qpid-java-broker-7.1.5
            Reporter: Alex Rudyy
            Assignee: Alex Rudyy
             Fix For: qpid-java-broker-7.1.6

A defect was found in changes for method {{AbstractQueue#visit()QueueEntryVisitor}} introduced
as part of QPID-8273. In some rare circumstance the message references can be leaked (when
method {{#visitor()}} is called and entry is deleted between call to {{QueueEntryIterator#advance}}
and {{org.apache.qpid.server.queue.QueueEntry#newMessageReference}} ), which could result
in unexpected message references left behind. Potentially, the persistent message can be left
un-deleted after removal of queue entry.
