I'm just suggesting that we allow null and null-filled but don't allow something (null filled array of wrong length) that would have been rejeceted in previous JDK versions. I would also suggest to check the length before the content - in case an array is supplied.

Hmmm... the spec still says:

     * @throws IllegalArgumentException if <code>names</code> or
     * <code>filters</code> is null, or if <code>names</code> contains
     * a null element, or if the three arrays do not all have the same
     * size.
 ```
