public class SuperStackClassLoader
extends java.lang.ClassLoader

A Classloader that will load classes from a module but then accend the superstack of a request to find classes in calling contexts. It also contains a cache which improves performance with some of the liberal ways that classloaders are used in scripting engines. This includes caching of not found exceptions. This classloader adds an overhead as compared to the regular module classloader however it gives classloading which is strictly according to the same model as used in resource resolution- this however is rarely needed.
