> Durable subscriptions do not work in 5.10 and 5.11-SNAPSHOT.
> Test case:
> Run default broker.
> . Connect "client1" with clean_session=true.
> . Subscribe to topic "paho/test"
> . Disconnect client1
> . Connect "client1" with clean_session=false
> . Subscribe to topic "paho/test"
> . Disconnect "client1"
> . Connect "client2"
> . Publish message "hello world" to topic "paho/test"
> . Disconnect "client2"
> . Connect "client1" with clean_session=false
> . Subscribe to topic "paho/test"
> . Verify that the message is received.
