             Summary: Domain graceful shutdown may attempt to use an AbstractMessageHandler that is shutdown
                 Key: WFCORE-199
                 URL: https://issues.jboss.org/browse/WFCORE-199
             Project: WildFly Core
          Issue Type: Bug
          Components: Domain Management
    Affects Versions: 1.0.0.Alpha10
            Reporter: Brian Stansberry


ManagedServer during shutdown tries to send a "shutdown" op to the remote server, triggering a graceful suspend.

Problem is, the TransactionalProtocolClient it uses is using a ManagementChannelHandler that may have been shut down. The service that controls the lifecycle of the ManagementChannelHandler (i.e. ManagementChannelOpenListenerService) is written to ensure that it isn't shutdown open until incoming requests complete, but there is nothing preventing shutdown when client uses are desired.

The specific area where this can be a problem is the assert !shutdown at

https://github.com/wildfly/wildfly-core/blob/master/protocol/src/main/java/org/jboss/as/protocol/mgmt/ActiveOperationSupport.java#L151

One possible solution is to distinguish locally initiated active operations from remote ones. AIUI the goal is to reject further remote ones.
