Based on information from AMQ team (ENTMQBR-1818) this issue is no longer present. Setting as resolved.

>             Project: WildFly
>          Issue Type: Bug
>          Components: JMS
>    Affects Versions: 14.0.0.Final
>            Reporter: Miroslav Novak
>            Assignee: Martyn Taylor
>            Priority: Critical

> Test Scenario:
> * Start 2 servers in colocated topology with shared store
> * Start procuder and consumer sending/receiving messages to/from queue on 1st server(to live)
> * Kill 1st server and wait for backup on 2nd server to start
> * Clients failover to backup to 2nd server and wait for them to finish
> * Check that number of sent/received messages is the same
> Result:
> Sometimes happens that clients do not failover to backup to 2nd server and retry connection. I can see that backup on 2nd server started and created cluster with colocated live server but clients did not connect to it.
> Clients are retrying connection:
