Hi, Please review http://cr.openjdk.java.net/~henryjen/ccc/8009736.2/webrev/
Highlight of changes, - Comparators class is now only package-private implementations. The public static methods have been move to other arguably more appropriate places, mostly in Comparator. - Comparator.reverseOrder() is renamed to Comparator.reversed() - nullsFirst(Comparator) and nullsLast(Comparator) are introduced to wrap up a comparator to be null-friendly. To see the API changes, found the specdiff at http://cr.openjdk.java.net/~henryjen/ccc/8009736.2/specdiff/overview-summary.html Cheers, Henry
