> I've attached a patch for various correctness issues in our collections:
>  - Maps with null values used to think they were equal to every other map with the same size.
>  - Map.equals() and Set.equals() didn't recover from NPEs in contains().
>  - singletonMap()'s entry didn't implement toString().
>  - TreeMaps with natural ordering permitted a null element, if it was the first element ever added.
>  - TreeSets didn't return the right status messages on add() and remove() when nulls were in play.
