Subject [jira] [Resolved] (AMQ-4501) Failover priorityBackup doesn't work if client accepts updates to its list of known URIs from the broker.

Timothy Bish resolved AMQ-4501.
-------------------------------

    Resolution: Fixed
      Assignee: Timothy Bish

Fixed on trunk.  In practice its fine to have the clients updated with new brokers but you
really don't want to combine priority backup and cluster rebalance as the clients that are
on the priority backup will ignore any rebalance requests.

> If a client has priorityBackup enabled and connects to a broker in a cluster with updateClusterClients="true"
in its transport connector, the client ignores the priorityBackup flag it connects to any
URI received from the broker, even if that URI doesn't have priority.
> This is easy to reproduce adding a test case to the activemq-unit-tests/src/test/java/org/apache/activemq/transport/failover/FailoverPriorityTest.java
test suite.
