public class TemporaryClassLoader
extends URLClassLoader

ClassLoader implementation that allows classes to be temporarily loaded and then thrown away. Useful for verifying and inspecting a class without first loading(and thus polluting) the parent ClassLoader.

This class is a proper subclass of URLClassLoader. This class will locally load any class except for those defined in the java.*, javax.* and sun.* packages and annotations all of which are loaded by with Class.forName(name, resolve, getClass().getClassLoader())
