Problem with latest 4.1 SNAPSHOT when broker name is set
Folks, there is a problem with the latest 4.1 SNAPSHOT when a broker
name is set. It causes 2 brokers to be created... and I think it is
because of the newly added CommandAgent service which is added to the
brokers default services when started. It is using vm://localhost,
which appears to be creating a new Broker using the name "localhost"
when the broker it is attached to has a different name.
For example:
<snip>
BrokerService broker = new BrokerService();
broker.setBrokerName("foo");
broker.start();
</snip>
Will end up creating a broker name "foo" and then another named
"localhost".
Where, this will create one broker, named "localhost":
<snip>
BrokerService broker = new BrokerService();
broker.start();
</snip>
I'm not really sure how vm://* works with respect to broker names...
so I can not say for sure what the fix is, or why this is happening.
But I can say for sure that the above snips create 2 and 1 brokers
respectively.
We noticed this while trying to track down a rouge activemq-data
directory which kept popping up in Geronimo, which for some reason
had its broker gbean set to create a broker with the name "possibly-
unique-broker". I've fixed this by only setting the broker name if
it is non-null, and then commenting out the brokerName attributed in
the plan, but something is definitely broke on your side of the fence
wrt broker names and vm:// transports.

Yep.. looks like problem with the CommandAgent. The
vm://${brokerName} connector will start up a broker named
${brokerName} if it is not already running. I just need to adjust the
start up code so that the command agent is set with the right
connection URI.
