code: public static void loadProperties (String path, ClassLoader loader, Properties target)
          throws IOException
      {
          InputStream in = getStream(path, loader);
          if (in == null) {
              throw new FileNotFoundException(path);
          }
          target.load(in);
          in.close();
      }
docs: Like {@link #loadProperties(String,ClassLoader)} but the properties are loaded into the
  supplied {@link Properties} object.
