Description
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.
Added support for a new JMX property - ReplyThreadCount to service Performance MBean. Also, added log message identifying number of consumers on a reply queue. Updated docs to include the new JMX property on service Performance MBean.
