> In {{SequentialAccessSparseVector}} a bug is noted.  When Cuonting Non-Zero elements {{NonDefaultIterator}} can, under certain circumstances give an incorrect iterator of size different from the actual non-zeroCounts.
> {code}
>  @Override
>   public Iterator<Element> iterateNonZero() {
>     // TODO: this is a bug, since nonDefaultIterator doesn't hold to non-zero contract.
>     return new NonDefaultIterator();
>   }
> {code}
