public class HelmaClassLoader
extends java.net.URLClassLoader

Classloader used for application class loading. The main purpose of this class is to make protected addURL visible to the org.helma.javascript package. FIXME: class lookups are cached, so adding a jar file after a class has already been looked up won't make the classes available. Maybe we should go with disposable classloaders and create a new one for each added URL.
