> Specs 1.5
> Methods throws 
>   NullPointerException - if a is null. 
>   IndexOutOfBoundsException - if offset or count is negative, or if offset + count is larger than the length of the given array.
> If first argument is null RI throws NPE only in the second test, it's strange, but we have to follow.
