----------------------------------------

             Summary: Domain server process' main thread can terminate without triggering process exit
                 Key: WFCORE-1848
                 URL: https://issues.jboss.org/browse/WFCORE-1848
             Project: WildFly Core
          Issue Type: Bug
          Components: Domain Management
            Reporter: Brian Stansberry
            Assignee: Brian Stansberry


If a thread completes the DomainServerMain main(String[] args) method, the process must exit. Currently that may not occur, as this stack trace reported while manually checking the WFCORE-1844 fix showed:

If the process does not exit, it is no longer under the control of the PC or HC and the only thing they can do with it is kill it. So it should kill itself.
