Error description

  • When a new collaboration session is started, several events
    get added to an internal queue which can later be fetched
    with a GET /event API call.  In the problematic case, the user
    tries to start a session with invalid inputs first and quickly
    follows it with a second attempt with the right inputs
    (correctly identifying  the party to collaborate with).
    At that point, the GET /event API is called which returns
    all the events up to that point, including those from the
    failed attempt.  Therein lies the problem.  The event list
    contains a "NOT_ESTABLISHED" event from the first
    failed attempt, but that causes potential client code
    to associate it with the second successful attempt.

    ****************************************************************
    The GET /event REST API may retrieve invalid data when a
    failed attempt to use the REST interface is followed by a
    successful one.
    

Problem conclusion

  • This problem was fixed by draining old events when a new
    collaboration was being enabled or started.
    
    The fix for this APAR is currently targeted for inclusion in
    CEA fix pack 1.0.0.7. Please refer to the Recommended Updates
