[AMQ7] Exclusive Queues behaviour in clustered environment

Issue

• How Exclusive Queues will behave in a clustered environment?

• Created AMQ Broker cluster with two instances. [i.e., Broker_POD1 & Broker_POD2]

• Created an exclusive queue [i.e., queue://TEST/EXCLUSIVE_QUEUE]

• Execute the commands in the exact order:

  1. Send "Test1" to queue://TEST/EXCLUSIVE_QUEUE@Broker_POD1
  ./artemis producer --url tcp://<Broker_POD1_IP>:61616 --user <username> --password <password> --destination 
  queue://TEST/EXCLUSIVE_QUEUE --message-count 1 --message Test1
  
  2. Send "Test2" to queue://TEST/EXCLUSIVE_QUEUE@Broker_POD2
  ./artemis producer --url tcp://<Broker_POD2_IP>:61616 --user <username> --password <password> --destination 
  queue://TEST/EXCLUSIVE_QUEUE --message-count 1 --message Test2
  
  3. Send "Test3" to queue://TEST/EXCLUSIVE_QUEUE@Broker_POD1
  ./artemis producer --url tcp://<Broker_POD1_IP>:61616 --user <username> --password <password> --destination 
  queue://TEST/EXCLUSIVE_QUEUE --message-count 1 --message Test3
  
  4. Consume 3 messages from queue://TEST/EXCLUSIVE_QUEUE@Broker_POD1 with Single Thread.
  ./artemis consumer --url tcp://<Broker_POD1_IP>:61616 --user <username> --password password> --destination 
  queue://TEST/EXCLUSIVE_QUEUE --message-count 3 --data out.txt
  

• But messages are received in incorrect order as shown below Test1, Test3 followed by Test2

  • sh-4.4$ cat out.txt:

    Test1
    Test3
    Test2
    Test1
    Test3
    Test2
