      Scenario

      • There are 4 Wildfly servers. Severs 1, 3 are in cluster.
      • Queue InQueue is deployed to servers 1,3.
      • Servers 2 and 4 have RA configured to connect to servers 1 and 3 server.
      • Start servers 1,3 and send 10000 (~1Kb) messages to InQueue
      • Start servers 2,4 with MDB consuming messages from InQueue and sending to OutQueue.
      • When MDBs are processing messages, restart (clean shutdown and start) servers in this order: 1,2,4,3
      • Wait until all messages are processed.
      • Measure number of consumers on InQueue on servers 1 and 3.
      • Difference between number of consumers must be <= 2.

      Expectation: Number of consumers on servers 1 and 3 are almost equal.
      Reality: Number of consumers on servers 1 and 3 are sometimes different. E.g. server 1 has 19 consumers and server 3 has 11 consumers.

      Note: this is not regression. I can see this issue also with Artemis 1.5.x.
