----------------------------------------------
Key: AMQ-2329
URL: https://issues.apache.org/activemq/browse/AMQ-2329
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.2.0
Reporter: craig mcmillan
after correct operation for some time, an NPE in the broker renders the broker
inoperable. restart is required
these mails describe two instances of what seem to be the same problem :

below is activemq related logging from broker start to failure. info level and
above only unfortunately
the tcp:///127.0.0.1:55870 is a client connection
i only have one broker. there were two clients, one in the same vm, producing
only, and one in a different vm both consuming and producing, each using a
single tcp connection
