Add JGroups-based SingletonServiceBuilderFactory implementation --------------------------------------------------------------- Key: WFLY-7100 URL: https://issues.jboss.org/browse/WFLY-7100 Project: WildFly Issue Type: Enhancement Components: Clustering Affects Versions: 10.1.0.Final Reporter: Paul Ferraro Assignee: Paul Ferraro Fix For: 12.0.0.Final The singleton subsystem currently requires the Infinispan subsystem. To minimize the requirements for using the singleton subsystem within the context of the host-controller, we should reimplement singleton service using JGroups directly, instead of requiring an Infinispan cache.
