[Adrian Brock (JIRA)]

Better signalling of shutdown
-----------------------------

                 Key: JBAS-5328
                 URL: http://jira.jboss.com/jira/browse/JBAS-5328
             Project: JBoss Application Server
          Issue Type: Sub-task
      Security Level: Public (Everyone can see)
          Components: MicroContainer bus
            Reporter: Adrian Brock
         Assigned To: Adrian Brock
             Fix For: JBossAS-5.0.0.CR1


Currently within the shutdown we generally just do something like

AtomicBoolean shutdown = new AutomaticBoolean(false);

public void shutdown()
{
   while (still deployments)
     removeDeployments();
  shutdown.set(true);
}

public void deploy()
{
   if (shutdown.get())
     throw new IllegalStateException("Already shutdown");
}

This needs improving to
1) Have a prepareShutdown() so we can signal that new deployments are not allowed earlier
2) The IllegalStateException should be replaced with a ShutdownException such that the caller
can ignore such errors and deal with the shutdown more gracefully
