Description

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.
