org.springframework.xd.module.support.NullClassLoader

public class NullClassLoader
extends java.lang.ClassLoader

A ClassLoader that can't find or load anything. Useful for insulating a (parent last) child ClassLoader from the main runtime classpath, in cases where it is expected that a class or resource will be resolved by the child ClassLoader. In effect, using an instance of this class as a parent ClassLoader is equivalent to using no-parent, as it would always fail.
