----------------------------------

             Summary: ClassNotFoundException when creating singleton service via SingletonPolicy
                 Key: WFLY-6265
                 URL: https://issues.jboss.org/browse/WFLY-6265
             Project: WildFly
          Issue Type: Bug
          Components: Clustering
    Affects Versions: 10.0.0.Final
            Reporter: Paul Ferraro
            Assignee: Paul Ferraro
             Fix For: 10.1.0.Final


This is because the org.wildfly.clustering.singleton.SingletonPolicy interface references org.wildfly.clustering.service.Builder from the org.wildfly.clustering.service module, but this module is not exported to deployments.
