Bhavani Iyer updated UIMA-1617:
-------------------------------

    Attachment: UIMACPP-1617.patch

Modified the C++ service wrapper to handle QUIESCEANDSTOP request   The wrapper will call stop() on the Connection to stop dispatch of message.  It will allow processing threads to complete current work, send a DONE message to the Java controller and terminate the C++ process.

The UIMA-1616 patch is required for compatibility with the Java UimacppServiceController.

> The C++ service wrapper needs to be modified to handle quiesce and shutdown requests from the command line as well as from a Java controller.
> A 'q' entered at the command line should  cause the wrapper to wait for the processing instances to complete the current work before shutdown.  A 's' entered at the command line should  result in an immediate shut down. Ctrl C is to be handled as a quiesce and shutdown.
