/**
 * Thrown when a null argument has been given to a method that doesn't accept them.
 * This exception extends {@link NullPointerException} in order to stress out that
 * the error is an illegal argument rather than an unexpected usage of a null pointer
 * inside a method body.
 *
 * <div class="note"><b>API note:</b>
 * We could argue that this exception should extend {@link IllegalArgumentException}.
 * However {@link NullPointerException} has become a more widely adopted practice and
 * is now the recommended one in the <cite>Effective Java</cite> book.</div>
