> 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.
