             Summary: Singleton deployments does not work in domain mode
                 Key: WFLY-8706
                 URL: https://issues.jboss.org/browse/WFLY-8706
             Project: WildFly
          Issue Type: Bug
          Components: Clustering
    Affects Versions: 10.1.0.Final
         Environment: Centos
Wildfly 10.1.0.Final (two instances and one domain controller)
Java 8

            Reporter: Ariel Carrera
            Assignee: Paul Ferraro


In a domain mode, when a deployment is a "singleton deployment" (with a singleton- deployment.xml descriptor), it is working fine if the sever 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 deployed.
