[jboss-jira] [JBoss JIRA] (WFLY-5612) UnsupportedOperationException on SingletonService.getValue()

[Paul Ferraro (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-5612?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13123954#comment-13123954 ] 

Paul Ferraro commented on WFLY-5612:
------------------------------------

Couple things:
# Under which server profile does this test run?
# org.wildfly.clustering.server is a private module.  Singleton services should be created using the public module.  e.g. https://github.com/wildfly/wildfly/blob/9.x/testsuite/integration/clustering/src/test/java/org/jboss/as/test/clustering/cluster/singleton/service/MyServiceActivator.java
