A somewhat related issue is how component deployers support fine grained hot deployment. For example, if servlets, jsp, ejb, etc should be redeployable by just updating the class file to pickup business logic only changes, the deployers need to isolate such components in bundles that have no exports of resources/types. This should just be class loading metadata associated with the component that ties into the class loading model.
