code: public static String simpleObjectName(Object object) {
          if (object == null) {
              return "<null>";
          }
          StringBuilder builder = new StringBuilder();
          builder.append(simpleClassName(object.getClass()))
              .append('#')
              .append(objectId(object));
          return builder.toString();
      }
docs: Returns the simple name of the object's class together with an id
  (see {@link #objectId(Object)}). Can be used to create a human
  readable, though not necessarily unique, label for an object.
  
  @param object
