> If you create a UnarySequence<?> with an ArrayList that contains a null element
and execute the run method, you will receive a NullPointerException. 
> The same happens when you use the constructor UnarySequence(UnaryProcedure<? super
A>... procedures). A null procedure is converted into a list with the null object as the
sole element.
