> The RankingComparator class is used for two cases: ordering ConfigurationPlugin services as per the service.cmRanking property and ordering services as per the service.ranking property. These orderings are slightly different for which the class does not provide properly:
> * service.cmRanking sorts ascending and does not define an order amongst services with the same cmRanking value
> * service.ranking sorts in descending property value order and defines to fall back to service.id ordering (ascending) in case of equal service.ranking values.
> The RankingComparator should be fixed (and simplified) to cope with these two mechanisms.
> This should also be tested using unit tests.
