      1. Setup a pair of WildFly 13 beta servers with required user and standalone-ha.xml configuration:

      ./node1/bin/add-user.sh -a -g users -u joe -p joeIsAwesome2013!
./node1/bin/standalone.sh -c standalone-ha.xml -b 127.0.0.1 -bmanagement 127.0.0.1 -Djboss.node.name=node1
./node2/bin/add-user.sh -a -g users -u joe -p joeIsAwesome2013!
./node2/bin/standalone.sh -c standalone-ha.xml -b 127.0.0.2 -bmanagement 127.0.0.2 -bprivate 127.0.0.2 -Djboss.socket.binding.port-offset=100 -Djboss.node.name=node2

      2. Deploy project in repro.zip according to its readme file.
      3. Start the remote EJB client according to the readme file. Notice that the EJB client is not following the weak affinity configured in its InitialContext.

    • Regression

    Description

      Remote EJB client with InitialContext setting up weak affinity will not hold up the affinity, resulting in a behaviour that's different to previous releases of WildFly. In previous versions of WildFly, java.naming.provider.url property of InitialContext was enough to enforce weak affinity to a node in remote EJB client.

      This is a regression compared to WildFly 12. The client version does not change the behaviour, which leads me to believe the issue is server-side.

      Update: The issue affects only stateful bean invocations.
