    if ( clazz.getSuperclass( ) == Object.class )

    There are 2 problems with your original implementation:

    1. getSuperclass may return null and you get NPE when you call getName
    2. You use identity equality with a String ( == instead of equals ). Strangely enough it may work in this case as "java.lang.Object" string is probably internalized.
