Date Thu, 06 Feb 2014 10:56:09 GMT
Aki Yoshida created CXF-5546:
--------------------------------

             Summary: NPE may be thrown and logged during WS-RM's retransmission
                 Key: CXF-5546
                 URL: https://issues.apache.org/jira/browse/CXF-5546
             Project: CXF
          Issue Type: Bug
          Components: WS-* Components
    Affects Versions: 2.7.9
            Reporter: Aki Yoshida
            Assignee: Aki Yoshida


While a message is being retransmitted from a client (RM-Source) from its retransmission queue,
the corresponding message might be acknowledged and its resource released at the client. And
in this case, an NPE will be thrown during the resending of the message.

WARNING: WS-RM retransmission failed.

Note that this issue is about handling this case gracefully to avoid throwing an NPE. The
issue itself does not break the delivery guarantee semantics as the resend is failing because
the message has been acknowledged.
