    *                      session causes a memory leak in         *

    * RECOMMENDATION:                                              *
    ****************************************************************
    When the timer is canceled and the application session is not
    valid, we need to remove the timer from the session repository
    map directly. Otherwise it is still unremoved and that causes a
    memory leak.
    

Problem conclusion

  • The code has been fixed to remove the timer object
    from the session repository map when the application session
    on which the timer was invoked is not valid.
    

Temporary fix
