      Obtain the application to deploy

      git clone git@github.com:clusterbench/clusterbench.git
cd clusterbench
mvn install -q -P singleton-deployment-specific-descriptor -DskipTests -Denforcer.skip=true

      after the build completes, you will have clusterbench-ee10-ear/target/clusterbench-ee10.ear

      Start a cluster

      Start a 4 nodes cluster using the standalone-ha.xml profile

      deploy the application

      deploy the the clusterbench-ee10.ear application on all nodes

      create replicated sessions

      make some HTTP calls to every node to the context path /clusterbench/session: this will cause some HTTP sessions to be created and replicated across the cluster nodes

      simulate fail-over

      • Shutdown and restart node1
      • Shutdown and restart node2
      • Shutdown and restart node3
      • Shutdown and restart node4

      Scenario: we have a 4 nodes cluster where we deploy a singleton-deployment application;

      When the nodes are stopping, on some of them, we observe the following error:
