      Steps to reproduce
      1. Install JBoss EAP 7.2.x.
      2. unzip test.zip under the EAP_HOME
      3. Execute the following commands under the EAP_HOME/bin.
      Run a proxy server

      $ ./standalone.sh

      Run nodes

      # node1
$ ./standalone.sh -c standalone-ha.xml -Djboss.server.base.dir=../node1 -Djboss.server.config.dir=../standalone/configuration/ -Djboss.server.name=node1 -Djboss.socket.binding.port-offset=100

# node2
$ ./standalone.sh -c standalone-ha.xml -Djboss.server.base.dir=../node2 -Djboss.server.config.dir=../standalone/configuration/ -Djboss.server.name=node2 -Djboss.socket.binding.port-offset=200

      4. Open http://localhost:8080/test-jsf/view.jsf
      5. If you push the submit button, the following error would be output either node.

      In the round-robin load-balancing environment, IllegalStateException occurs with postback action.
      This issue seems to occur notably when set javax.faces.PARTIAL_STATE_SAVING=false.
