URLClassLoader. Mercury would be responsible for resolving and retrieving the dependencies which would then be used to populate a ClassRealm where there would be a connection to the host applications ClassRealm as the parent but the search order would be child first, and the parent ClassRealm can optionally choose to limit the searching to particular classes. The application ClassRealm, or parent ClassRealm, should only expose the API in the form of and application interface and model classes that may be required...

Notice how no connect events are fired for the second call. It reused the connection from the first request for dramatically better performance.
