> 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.
