Description

The broker failed to bind throwing:
BROKER: main 2010-02-10 13:24:30,472 ERROR [Qpid.Broker] Error initialising message broker: java.net.BindException: Could not bind to 0.0.0.0/0.0.0.0:15672
BROKER: java.net.BindException: Could not bind to 0.0.0.0/0.0.0.0:15672

BROKER: at org.apache.qpid.server.Main.<init>(Main.java:104)
BROKER: at org.apache.qpid.server.Main.main(Main.java:541)

So when it then goes to shutdown the QMF throws a NPE.

Now I can't tell if the broker always fails to shutdown QMF as the test profiles do not cleanly shutdown the broker. QTC test do an effective kill -9 on the external broker.
