  | Yeah i thought it's just a MC bean with an install callback :) It's just a question when this bean gets deployed. Basically there is no way we can eliminate deployment phases - where at the moment each Profile represents a deployment phase (mainDeployer.process()).
  | Just think what would happen if you move the "TomcatService" into the 'web.deployer'. This would start the connectors/acceptors/endpoints before even looking at what's in 'deploy'. Which means that the acceptor would be available, but without any web app installed. The same would happen if we have multiple smaller profile description.

  | Although this is not specific to graceful shutdown it could affect it depending on the way you signal the acceptors to gracefully stop. If the "central management bean" is called to signal the shutdown, before we actually stop AS then it could work. Otherwise the same would happen - we undeploy all user applications, before undeploying the acceptor deployment.

I agree with your conclusion "if the "central management bean" is called to signal the shutdown, before we actually stop AS then it could work." But I want to clarify some re: my understanding of the acceptor and how it ties in to deployment stages.

AIUI, an acceptor is not scoped to a connector. It's scoped to the thing that handles requests for a particular component (a webapp, and EJB). In Tomcat terms, it would be the first thing in the webapp-specific Pipeline that results in a call on the servlet.
