> 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.
