> UIMA AS two stop options dont seem to work reliably. Neither 's' nor 'q' on the command
line force a clean shutdown of the process. Actually, there is also a related problem. Namely,
when the shutdown succeeds it appears that the Shared Connection that all Spring listeners
use is not closed which leads to an ugly exception on the broker console. This happens every
time the service is terminated. Review listeners shutdown code and make sure that when the
last listener terminates the connection is stopped before the process exits. Also, make sure
that uima threads from custom pools are daemon threads to allow the jvm to collect them on
shutdown. NOTE: AMQ version 4.x internal threads are not daemon threads and there is special
code in the listener to wait for them to stop before exiting. Newer AMQ version use daemon
threads so shutting down AMQ is much more reliable.
