[jboss-jira] [JBoss JIRA] (WFLY-13376) Cannot change jgroups subsystem attribute without reload

Cannot change jgroups subsystem attribute without reload -------------------------------------------------------- Key: WFLY-13376 URL: https://issues.redhat.com/browse/WFLY-13376 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 19.0.0.Final Reporter: Paul Ferraro Assignee: Paul Ferraro Priority: Blocker We hit a change in behaviour while testing 7.4.0.CD19. In 7.3.0.GA and before it was perfectly fine changing jgroups attribute without reloading: {code:java} /subsystem=jgroups/channel=ee:write-attribute(name=cluster, value=anything){allow-resource-service-restart=true} {"outcome" => "success"} {code} Now with 7.4.0.CD19-CR1 it is no longer possible: {code:java} /subsystem=jgroups/channel=ee:write-attribute(name=cluster, value=anything){allow-resource-service-restart=true} { "outcome" => "failed", "failure-description" => "WFLYCTL0158: Operation handler failed: org.jboss.msc.service.DuplicateServiceException: Service org.wildfly.clustering.jgroups.channel.ee.captor is already registered", "rolled-back" => true } {code} Server log exception: {code:java} 18:20:19,676 ERROR [org.jboss.as.controller.management-operation] (management-handler-thread -
