             Summary: Removal of messaging-activemq's server stops Infinispan services
                 Key: WFLY-7384
                 URL: https://issues.jboss.org/browse/WFLY-7384
             Project: WildFly
          Issue Type: Bug
          Components: Clustering, JMS
            Reporter: Jeff Mesnil
            Assignee: Paul Ferraro


This issue occurs after I fixed the issue for WFLY-7333 which ensures that all services related to a messaging-activemq server are stopped when the server is removed.

When I run the command to remove the server:

/subsystem=messaging-activemq/server=default:remove

I see logs in the app server about Infinispan services being stopped:

There should be no reason than stopping the messaging server should stop such Infinispan services. The messaging-activemq subsystem has *no* dependency to Infinispan resources.
However both messaging-activemq and infinispan resources depends on JGroups resources.

I did a diff of the services dump before and after removing the messaging-activemq server (see attached file).
The Infinispan services are stopped as a consequence of stopping the jboss.messaging-activemq.default service. Before removing the server, this service is in this state:

{noformat}
Service \"jboss.messaging-activemq.default\" (class org.wildfly.extension.messaging.activemq.ActiveMQServerService) mode ACTIVE state UP (parent: jboss.as.server-controller) (dependencies: org.wildfly.management.jmx, org.wildfly.clustering.jgroups.default-channel-factory, jboss.outbound-socket-binding.http, jboss.binding.http, jboss.http-upgrade-registry.default, jboss.path.manager, jboss.security.security-domain.other)
{noformat}

The only relation between this messaging server and the Infinispan resources is that they depend on the org.wildfly.clustering.jgroups.default-channel-factory service. Before removing the messaging server, this service is in the state:

{noformat}
Service \"org.wildfly.clustering.jgroups.default-channel-factory\" (class org.jboss.msc.service.ValueService) mode PASSIVE state UP (parent: jboss.as.server-controller) (dependencies: org.wildfly.clustering.jgroups.channel-factory.ee)
{noformat}

After removing the messaging server, this service is in the state:

{noformat}
> Service \"org.wildfly.clustering.jgroups.default-channel-factory\" (class org.jboss.msc.service.ValueService) mode PASSIVE state DOWN (WAITING) (parent: jboss.as.server-controller) (dependencies: org.wildfly.clustering.jgroups.channel-factory.ee)
{noformat}

I am not sure to understand why and when removing the jboss.messaging-activemq.default implies to remove the org.wildfly.clustering.jgroups.default-channel-factory service but there is no reason that removing any messaging-activemq resources should impact the state of Infinispan services
