UIMA AS aggregate doesnt handle service broker restart
------------------------------------------------------
Key: UIMA-1704
URL: https://issues.apache.org/jira/browse/UIMA-1704
Project: UIMA
Issue Type: Bug
Components: Async Scaleout
Reporter: Jerry Cwiklik
Fix For: 2.3AS
If a delegate service broker is restarted, the aggregate client doesnt attempt
to recreate a listener to a temp reply queue. This may cause a hang or a
timeout in the aggregate client. In this scenario there are two brokers: one
managing aggregate service queue and a second that manages delegate service
temp reply queue. When the latter is restarted, the dispatch code does not
attempt to create a new listener. The aggregate code should detect a failure of
the broker, mark a delegate as FAILED and kill the listener. On subsequent CAS
request, the aggregate should attempt to create a new listener and a new JMS
Connection to a broker. Failure to re-establish the connection is subject to
error handling as defined in deployment descriptor Process error configuration
for the delegate.
