Justin Bertram updated ARTEMIS-5551:
------------------------------------
Description:
I have a Quarkus application connecting to a HornetQ broker (cluster of 2
replicas). We are using the {{artemis-hqclient-protocol}} version 2.41.0.
When shutting down one member, my application continues to work on the other
member, but several error messages gets logged including the following NPE:
2025-06-23 11:54:31,746 ERROR [org.apache.activemq.artemis.core.client]
