            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik
             Fix For: 2.5.0AS


Looks like there is a race condition that results in calling onBeforeProcess() callback twice. Seems like a thread handling Process reply is racing with another thread handling service ACK. Synchronize code to make sure only one of the two threads calls onBeforeProcess() callback
