------------------------------

             Summary: Race condition causes NullPointerException in DemandForwardingBridgeSupport.collectBrokerInfos
                 Key: AMQ-5315
                 URL: https://issues.apache.org/jira/browse/AMQ-5315
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.10.0
            Reporter: Lee Butts
            Priority: Critical


We have seen the following NPE setting up a demand forwarding bridge
{code}
java.lang.NullPointerException: null
	at org.apache.activemq.network.DemandForwardingBridgeSupport.collectBrokerInfos(DemandForwardingBridgeSupport.java:365)
[activemq-broker-5.10.0.jar:5.10.0]
	at org.apache.activemq.network.DemandForwardingBridgeSupport.access$400(DemandForwardingBridgeSupport.java:105)
[activemq-broker-5.10.0.jar:5.10.0]
	at org.apache.activemq.network.DemandForwardingBridgeSupport$5.run(DemandForwardingBridgeSupport.java:331)
[activemq-broker-5.10.0.jar:5.10.0]
	at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) [na:1.7.0_60]
	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) [na:1.7.0_60]
	at java.lang.Thread.run(Thread.java:745) [na:1.7.0_60]
{code}

Code should return if futureRemoteBrokerInfo.get() returns null and fireBridgeFailed() is
called
