Gary Tully commented on ARTEMIS-3323:
-------------------------------------
ARTEMIS-2650 changed the id from uuid based, which was unique but not
consistent to connection id based which was typically uuid and consistent but
not when a user set the clientId on the connection factory.
> Openwire messageId needs to be globally unique

> Key: ARTEMIS-3323
> URL: https://issues.apache.org/jira/browse/ARTEMIS-3323
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Broker, OpenWire
> Affects Versions: 2.13.0
> Reporter: Gary Tully
> Assignee: Gary Tully
> Priority: Major
> Fix For: 2.18.0
>
>
> The current openwire message id from a converted core message uses the
> connection id as the seed combined with the journal id. When a client id is
> specified on the core producer, the resulting message id may not be unique
> across brokers due to the alignment of journal ids.
> The result is potential duplicate suppression in error by an openwire client.
> This can happen for clusters or multiple standalone brokers.
> The fix is to combine the journal id with the broker node id, such that it is
> globally unique and static for the life of the broker, which is consistent
> for redelivery/failover reconnect
