/**
* Temporary workaround to support controlling the lifecycle of the webserver runtime portion of TomcatDeployer via a
* JMX service in the deploy directory. We want it in deploy so dependencies on services in deploy can be properly
* expressed. We want it as a JMX service so the ServiceBindingManager can alter the connector ports.
* <p>
* A more long term solution involves:
* <ol>
* <li>separating out the JBossWeb runtime aspects from TomcatDeployer and putting them in a separate class</li>
* <li>developing a ProfileService-based alternative to ServiceBindingManager</li>
* </ol>
* </p>
