The following is a webrev for proposed extension methods on Comparator (reverse and compose) as well as static combinator methods in Comparators for things like turning a T -> {Comparable,int,long,double} into a Comparator.

http://cr.openjdk.java.net/~henryjen/webrevs/8001667.0/

This allows things like:

people.sort(Comparators.comparing(Person::getName))

Comparator byLastFirst = Comparators.comparing(Person::getLastName) .compose(Comparators.comparing(Person::getFirstName))

Please review and comment.
