    Description

      NullPointerException is shown in server shutdown with an open CLI connection in current WFLY master since WFCORE 4.0.0.Alpha7.

      Start the server and open a CLI connection, then stop server with Ctrl + C. We will see

      13:15:09,136 ERROR [org.jboss.threads.errors] (management task-1) Thread Thread[management task-1,5,main] threw an uncaught exception: java.lang.NullPointerException
	at org.jboss.as.server.mgmt.ManagementWorkerService.stopDone(ManagementWorkerService.java:72)

      I assign this to David as it seems this is caused by WFCORE-3397 and https://github.com/wildfly/wildfly-core/pull/3072 Please feel free to reassign to correct person.
