URL: https://github.com/apache/activemq-artemis/pull/3635#issuecomment-867733772
this is a relatively small change to support the scenario called out in the
doc as being unsupported. The trigger is still remote demand, the difference is
that when we see remote demand "and" existing consumers that don't match
messages "or" we have no local consumers, we will attempt to redistribute.

> We are experiencing the following issue:
> # We configure an Artemis cluster with ON_DEMAND message loadbalacing and
> message redistribution enabled.
> # We then connect a single consumer to *queues.queue1* on node1 that has a
> message filter that does NOT match a given message.
> # Then we send a message to *queues.queue1* on node1.
> # Then we connect a consumer to *queues.queue1* on node2 that has a filter
> matching the message we sent.
> We now would expect that the message on node1 currently not having any
> matching consumers on node1 to be forwarded or redistributed to node2 where a
> matching consumer exists.
> However that is not happening the consumer on node2 does not receive the
> message and in our case the message on node1 expires after some time despite
> a matching consumer is connected to the cluster.
> In the described scenario when we disconnect the consumer on node1 (that does
> not match the message anyway) the message is redistributed to node2 and
> consumed by the matching consumer.
> If no consumer was connected to node1, a message is sent to node1 and only
> then a matching consumer is connected to node2 the message is forwarded to
> node2 as expected.
> So I guess the core problem is that message redistribution of messages on
> node1 is not triggered when a matching consumer is connected to node2 while a
> *any* consumer already exists on node1 no matter if it actually matches the
> given message.
> I attached a maven test case that illustrates the issue.
