FailoverTransport throws NPE
----------------------------

                 Key: AMQ-3782
                 URL: https://issues.apache.org/jira/browse/AMQ-3782
             Project: ActiveMQ
          Issue Type: Bug
          Components: Transport
    Affects Versions: 5.2.0
         Environment: debian java-6-sun activemq 5.2
            Reporter: Wojciech Oczkowski


Failover transport occasionally throws NullPointerException

INFO   | jvm 1    | 2012/03/19 09:25:05 | Exception in thread "ActiveMQ Failover Worker: 2009192672"
java.lang.NullPointerException
INFO   | jvm 1    | 2012/03/19 09:25:05 |       at org.apache.activemq.transport.failover.FailoverTransport$2.iterate(FailoverTransport.java:125)
INFO   | jvm 1    | 2012/03/19 09:25:05 |       at org.apache.activemq.thread.DedicatedTaskRunner.runTask(DedicatedTaskRunner.java:98)
INFO   | jvm 1    | 2012/03/19 09:25:05 |       at org.apache.activemq.thread.DedicatedTaskRunner$1.run(DedicatedTaskRunner.java:36)

It seems like DedicatedTaskRunner starts Thread before FailoverTransport finish initializing
  reconnectTask field. 

Same code is present in 5.5.1 so it's possible that same bug is out there
