Several null handling bugs in collections
-----------------------------------------

                 Key: HARMONY-6396
                 URL: https://issues.apache.org/jira/browse/HARMONY-6396
             Project: Harmony
          Issue Type: Bug
          Components: JDK
         Environment: SVN Revision: 882389
            Reporter: Jesse Wilson
            Assignee: Jesse Wilson
         Attachments: Fixes_for_nullness_bugs_in_java_util.patch

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.
