> The description of the bug is as follows:
> *WMI: Inefficient use of keySet iterator instead of entrySet iterator
> (WMI_WRONG_MAP_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.
