public class ReloadingClassLoader
extends URLClassLoader

The classloader used by the reloader. Classes matching the include pattern are loaded using this classloader, and all of the files thus accessed are registered with the Reloader. When the Reloader determines that registered sources have changed it will discard the current instance of this classloader, thereby invalidating all classes, and discard all sessions.
