Description

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 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.
