https://issues.apache.org/jira/browse/AMQ-3438: Make use of remote port in Connection MBeanNames optional, useful when ephemeral range cycles quickly. added boolean attribute org.apache.activemq.broker.jmx.ManagementContext#allowRemoteAddressInMBeanNames, accessible via xml. when false, a transport connector will only be registered by its clientId (whic defaults to connectionid)
