> Details
> WMI_WRONG_MAP_ITERATOR: Inefficient use of keySet iterator instead of
> entrySet iterator
> This method accesses the value of a Map entry, using a key that was retrieved
> from a keySet iterator. It is more efficient to use an iterator on the
> entrySet of the map, to avoid the Map.get(key) lookup.
