/**
 * retrieve meta information for a UIMA-AS Service attached to a broker
 * It uses the port 1099 as the JMX port on the broker, unless overridden
 *   by defining the system property activemq.broker.jmx.port with a value of another port number
 * It uses the default JMX ActiveMQ Domain "org.apache.activemq", unless overridden
 *   by defining the system property activemq.broker.jmx.domain with a value of the domain to use
 *   This normally never needs to be done unless multiple brokers are run on the same node 
 *   as is sometimes done for unit tests.
