      Start a master slave pair of brokers (config attached) on one or two separate machines

      Once both brokers are up and running run junit test from test case

      mvn -Dtest=test_three test

      Once test is running do

      kill -SIGSTOP pid_master_broker

      Wait for slave broker to become active and look for two message in its log file:

      There seems to be a difference in time it takes for a client to reconnect to a slave broker after it becomes active.
      With AMQ 2.6 client runtime it takes about 2 seconds

      In both cases the same AMQ 7.5 broker is used.
