Keith Wall commented on QPID-3784:
----------------------------------
I think we should document the new parameter in the Programming in Apache Qpid
docbook. Also it might be worth pointing out in this JIRA that this patch will
revert the default behaviour back to that of Qpid 0.12.
> Add special JVM environment variable to run dispatcher thread as daemon/non
> deamon depending from its value.

> Dispatcher thread needs be set daemon/non-daemon depending of new
> configuration option to allow manipulating this behaviour.
> Historically, for the 0-8/0-9/0-9-1 client the use of Mina kept the
> JVM alive when a MessageListener was set, allowing asynchronous
> delivery to continue without the user having taken any explicit action
> to keep the JVM alive. Since we removed Mina this is no longer the
> case, and if there are no non-daemon threads then the JVM will now
> exit even though the user has set a MessageListener set. Investigating
> other providers suggests the typical behaviour is to make use of
> non-daemon threads by default, preventing this happening, but allowing
> users who desire that behaviour to configure it as such.
> For example, tibco seem to do exactly what I am proposing with their
> Dispatcher threads:
> https://docs.tibco.com/pub/enterprise_message_service/6.1.0-august-2011/doc/html/tib_ems_api_reference/api/javadoc/com/tibco/tibjms/Tibjms.html#PROP_DAEMON_DISPATCHER
> ActiveMQ seems to control this through transport options, defaulting
> to non-daemon threads with an option to reconfigure it:
