[classlib][luni] java.util.HashMap:avoid expand backed element array more than once. 
-------------------------------------------------------------------------------------

                 Key: HARMONY-1493
                 URL: http://issues.apache.org/jira/browse/HARMONY-1493
             Project: Harmony
          Issue Type: Improvement
            Reporter: Leo Li


Current implementation of HashMap.putAll() in Harmony just calls super.putAll() which ultimately
will call HashMap.put(), while this way might lead to expand the backing data array more than
once if the elements in the added Map is sufficiently large. However, the situation is able
to  be avoided, since we actually know the size of the added Map, thus the expected HashMap
capacity.
