UIMA AS Aggregate not exposing number of consumer threads on its delegate's reply queues
----------------------------------------------------------------------------------------

                 Key: UIMA-1742
                 URL: https://issues.apache.org/jira/browse/UIMA-1742
             Project: UIMA
          Issue Type: Bug
          Components: Async Scaleout
    Affects Versions: 2.3AS
            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik
            Priority: Minor


UIMA AS Spring listener uses a single thread per delegate to handle replies. If a deployment
descriptor is configured to process replies using multiple threads, the UIMA AS creates a
concurrent listener with a thread pool to which the single-threaded Spring listener delegates
all reply messages. This logic was added to assure that the parent CAS is always processed
ahead of its children. The problem is that a JMX console shows a single JMS Consumer on a
reply queue. This is correct, but the number of threads in the concurrent listener should
be shown in the UIMA AS MBeans.
