             Summary: CLI instance hanging around after test suite run
                 Key: WFCORE-203
                 URL: https://issues.jboss.org/browse/WFCORE-203
             Project: WildFly Core
          Issue Type: Bug
          Components: CLI
            Reporter: Stuart Douglas
            Assignee: Alexey Loubyansky


After a test suite run I see a CLI instance that has locked up. The issue is that remoting is not shutting down cleanly for some reason, which causes the shutdown hook thread to block. 

Even though the remoting threads are deamon threads, the shutdown thread is not, so it is actually the shutdown thread the is preventing the JVM from terminating. 


Relevant stack traces are:
