      In a domain mode, when a deployment is a "singleton deployment" (with a singleton- deployment.xml descriptor), it is working fine if the server nodes are started sequently but fails if it is started from domain console.
      When a deployments needs to be updated, a race condition happens and two instances of the deployment are started.
