Bhavani Iyer updated UIMA-1616:
-------------------------------
Attachment: UIMA-1616.patch
Modified quiesceAndStop() method to send a QUIESCEANDSTOP request to the C++
service.
This requires the patch in UIMA-1617 which modifies the C++ service wrapper to
process this request type. The C++ service wrapper will call the JMS
Connection stop() method to stop dispatch of new messages and allow the
processing threads to complete current work before shutting down the service.
A QUIESCEANDSTOP request is initiated when a 'q' is entered at the command
prompt or service is shutdown with CTRL C. The controller waits for an quiesce
done response from the service.
This patch also modifies the UimacppServiceController shutdown() api which is
used to stop the service immediately to wait for acknowledgment from the
service that shutdown was initiated.
