/**
 * Returns enumeration of local resources, combined with those of parent
 * class loader.//from ww w.j  a  v  a  2 s .c o m
 * 
 * The implementation of {@link #getResources(String)} is pretty
 * conservative. For a given resource name, only one resource URL will ever
 * be found from within the module hierarchy. Also, only the current module
 * is searched. It's ancestor and dependent modules are not searched for the
 * resource.
 * 
 * The module resource, if found, is returned as an {@link Enumeration}
 * which also includes the resources obtained from the standard or
 * application class loader via the super{@link #getResources(String)} call.
