Review comment:
Can you explain me what is this? just to make it easier for me to understand?
Is this a server with only the MQTT portion?
I can certainly hack your code and try to udnerstand.. just asking some
minimal english explanation to make my review easier.

> Key: ARTEMIS-2476
> URL: https://issues.apache.org/jira/browse/ARTEMIS-2476
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: MQTT
> Affects Versions: 2.10.0, 2.11.0
> Reporter: Assen Sharlandjiev
> Priority: Blocker
> Time Spent: 50m
> Remaining Estimate: 0h
>
> I have observed that new MQTT subscriptions on a given topic, receive older
> retained messages. Instead of getting the latest retained message published
> on the topic, the new subscription received an older message, published
> before that last one.
>
> I have created a [mqtt-test|https://github.com/assens/mqtt-test] project that
> demonstrated the problem. Check the readme, and run the Artemis broker test:
>
> mvn -Dtest=ArtemisTest verify
>
> The test project contains multiple MQTT brokers tests. Only Artemis broker
> tests fail.
