package org.jruby.runtime.load;
The ClassExtensionLibrary wraps a class which implements BasicLibraryService, and when asked to load the service, does a basicLoad of the BasicLibraryService. When the time comes to add other loading mechanisms for loading a class, this is the place where they will be added. The load method will check interface you can load a class with, and do the right thing.
