    1.36 + * <li>Accessing or modifying the field of a {@code null} object.
    1.37 + * <li>Taking the length of {@code null} as if it were an array.
    1.38 + * <li>Accessing or modifying the slots of {@code null} as if it
    1.39 + *     were an array.
    1.40 + * <li>Throwing {@code null} as if it were a {@code Throwable}
    1.41 + *     value.
    1.42 + * </ul>
    1.43 + * <p>
    1.44 + * Applications should throw instances of this class to indicate
    1.45 + * other illegal uses of the {@code null} object.

    1.47 + * {@code NullPointerException} objects may be constructed by the
    1.48 + * virtual machine as if {@linkplain Throwable#Throwable(String,
