The stack trace indicates that IP multicast must not be enabled on
your machine. To work around this, edit the conf/activemq.xml and:

1) Comment out the default-nc networkConnector. This networkConnector
uses multicast to automatically discover other ActiveMQ brokers.

2) Remove the discoveryUri attribute from the openwire transportConnector.

After making these changes, ActiveMQ won't use any IP multicast and
you shouldn't encounter the exception any longer.
