>             Project: WildFly
>          Issue Type: Enhancement
>          Components: JMS
>    Affects Versions: 10.1.0.Final
>            Reporter: Miroslav Novak
>            Assignee: Justin Bertram
>            Priority: Critical

> If MDB contains activation config property:
> @ActivationConfigProperty(propertyName = "rebalanceConnections", propertyValue = "true")
> so rebalancing of inbound connections is enabled then MDB is not able to failover from live to backup if backup is cleanly shutdowned (ctrl-c).
> Test scenario:
>  - There are 3 EAP 7 servers. 1st has Artemis configured as live and 2nd has Artemis configured as backup server. So servers are in dedicated HA topology with replicated journal. Then there are queues InQueue and OutQueue deployed to live and backup.
>  - Start live and backup and then send 2000 messages to InQueue to live server.
>  - Start 3rd server which has configured Artemis RA to connect to live server. HA is enabled. 
>  - Deploy MDB on 3rd server. MDB consumes messages from InQueue and sends to OutQueue in XA transaction.
>  - When MDB is processing messages cleanly shutdown live server. 
>  - MDB should failover to backup and process all the messages
>  - Receive messages from OutQueue from backup server and check that all messages were received.
> Test fails bacause MDB is not able to failover to backup.
> Server 3 with MDB is logging:
