> Removing the final element(s) in a MultiSet doesn't set the count on a MultiSet.Entry to zero.
> {code:java}
> protected int getCountAfterRemoval(MultiSet<String> multiset) {
>   MultiSet.Entry<String> entry = multiset.entrySet().iterator().next();
>   entry.getCount(); // = 2

>   entry.getCount(); // = 1
>   multiset.remove(entry.getElement());
>   return entry.getCount(); // Still = 1, should be 0
