Description

We have seen the following NPE setting up a demand forwarding bridge

java.lang.NullPointerException: null
	at org.apache.activemq.network.DemandForwardingBridgeSupport.collectBrokerInfos(DemandForwardingBridgeSupport.java:365) [activemq-broker-5.10.0.jar:5.10.0]

This occurred in one of our tests but only under load so seems to be a race condition of some sort.
