Previously, if you configured a slave broker to use a shared store and scaledown in a cluster, you could encounter an exception on the slave if the master broker went offline. This issue is resolved.

AMQ Broker 1839, AMQ Broker 1842, AMQ Broker 1845, AMQ Broker 0219, AMQ Broker 0519, AMQ Broker 1119
Using the following configuration on the slave where server1-connector points to another
broker in the broker cluster.
<ha-policy>
<shared-store>
<slave>
<failover-on-shutdown>true</failover-on-shutdown>
<restart-backup>true</restart-backup>
<scale-down>
<connectors>
<connector-ref>server1-connector</connector-ref>
</connectors>
</scale-down>
</slave>
</shared-store>
</ha-policy>
I am getting the following NullPointerException when the slave tries to activate.
