On lost connection to a broker UIMA AS Spring JMS listener excessively logs error msgs

                 Key: UIMA-2372
                 URL: https://issues.apache.org/jira/browse/UIMA-2372
             Project: UIMA
          Issue Type: Bug
          Components: Async Scaleout
            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik
             Fix For: 2.4.0AS

When UIMA AS service loses a connection to a broker, its JMS listener rapidly fills a log
with messages:

0 Feb 2012 12:33:33,598  WARN UIMA AS Service.UimaDefaultMessageListenerContainer - Could
not refresh JMS Connection for destination 'queue://<queue name>' - retrying in 5 ms.
Cause: Could not connect to broker URL:
tcp://<broker url>:61616?wireFormat.maxInactivityDuration=0. Reason: java.net.ConnectException:
Connection refused 

I've traced the origin of this message to Spring Framework's DefaultMessageListenerContainer.java,
refreshConnectionUntilSuccessful() method. Spring is attempting to auto recover the connection
by continually testing broker connection until success. Each failure results in a log msg
at WARNING level.  

To fix this, UimaDefaultMessageListenerContainer should override Spring's refreshConnectionUntilSuccessful()
with its own implementation which logs the error once and silently retries until success.
