Brian D. Johnson updated AMQ-6188:
----------------------------------
Description:
It is possible for a queue to be garbage collected due to inactivity despite
undelivered {{PERSISTENT}} messages being present on the queue.
Order of events-
* unused queue is marked for garbage collection due to inactivity
* prior to garbage collection, an anonymous producer comes online, sending one
or more messages, then closing
** Note: the queue's {{lastActiveTime}} is not reset when an anonymous producer
is created because they are not bound to a destination at creation.
* queue with pending Message(s) is garbage collected
A simple fix for this seems to be resetting {{BaseDestination#lastActiveTime}}
to zero each time a message is sent
({{BaseDestination#messageDelivered(context, messageReference)}}).
I'll submit a PR with a patch shortly.
