> 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.
