Disable ActiveMQ multicast

The Multicast allows to route the same message to a number of endpoints and process them in a different way.

It seems ActiveMQ will look up all the activeMQ server in the intranet for multicast by default.

I found if my co-worker (in the same intranet) started activeMQ, then I would have the problem to start my activeMQ. It was probably caused by "multicast". To disable the multicast, open the file %ACTIVEMQ_HOME%/conf/activemq.xml and comment

<networkConnector name="default-nc" uri="multicast://default"/>
