641 more complex functionality, you should write your own class loader.
648 each class loader creates its own name space.

684 Suppose that a class loader CL loads a class including this code snippet.
687 CL also loads these classes (unless it delegates to another class loader).
699 Each class loader except the bootstrap loader has a
700 parent class loader, which has normally loaded the class of that child
701 class loader. Since the request to load a class can be delegated along this
702 hierarchy of class loaders, a class may be loaded by a class loader that
704 Therefore, the class loader that has been requested to load a class C
705 may be different from the loader that actually loads the class C.
706 For distinction, we call the former loader <em>the initiator of C</em>
707 and we call the latter loader <em>the real loader of C</em>.
710 Furthermore, if a class loader CL requested to load a class C
