[ https://issues.jboss.org/browse/WFLY-2548?page=com.atlassian.jira.plugin.... ] Paul Ferraro commented on WFLY-2548: ------------------------------------ I've created a separate org.wildfly.clustering.web.api module to contain the @Immutable annotation. This module should be added to the classpath of web deployments, regardless of whether the clustering modules are present. I've located the DUP that adds the org.wildfly.clustering.api and org.wildfly.clustering.singleton modules to the deployment classpath in the jgroups subsystem - since these are only relevant if this subsystem is installed. -- This message is automatically generated by JIRA.
