      The reproducer need Byteman installed and a default Broker running.

      https://github.com/agagliardi/reproducer-ENTMQBR-4988

       

      • Install Byteman
      • Running a broker with defaults
      • run the reproducer with:
        • export MAVEN_OPTS=-javaagent:$BYTEMAN_HOME/lib/byteman.jar=script:amqclient.btm
        • mvn clean compile exec:java -Dexec.arguments="tcp://xxxxx:61616"
      • produce some message on
         ./artemis producer --destination topic://test --message-count 10 --message-size 10 --user admin --password admin --url tcp://xxxxx:61616
      • the reproducer will receive a message a will wait 30 sec to break the network before trying the rollback
          Byteman wait 30 second before ClientSessionImpl#flushAcks.
      • break the network, with iptables for example
      • wait that the rollback failure
      • fix the network (delete iptables rule)
      • press ENTER on the reproducer stdin
      • the reproducer stuck on the message Setting echo listener, now message should be received but will not as it's a bug.

       

       

      It seems that the ClientSession is no more able to recover after an exception during the rollback.
