    MainDeployer.stop

      So related to:
      http://jira.jboss.com/jira/browse/JBAS-1997

      There simply is no consistent notion of stopping a deployment as opposed to undeploying it. I have fixed the module type issue, and what happens now in the org.jboss.test.deployment.DeploymentTestCase.testListStartStopModules is that stopping the ear results in undeployment of the ejb and war modules, but does nothing to the ear deployment. The undeployment of the war/ejb do not result in removal of the jsr77 mbeans because the notification listener does not expect that a stop event equates to undeployment.

      Attempting to start the ear after this therefore results in error regarding duplicate jsr77 mbeans, and there is also a problem starting the war as the deployer cannot go from the stop state to the start state:

      olicyConfiguration.java:196)
      



      In general, I don't see that we have a meaningful implementation of start/stop for our deployers based on MainDeployer ops. Until they are rewritten with these states in mind, there is no meaningful mapping of the DeploymentManager.start/stop operations.

      The alternative is to write a jsr88 facade to the MainDeployer that explicitly honors the distiction between distribution and starting, stopping and removal.
