Reinier-

MinReducer and MaxReducer were concrete classes, not abstract interfaces.
The BGGA port of ForkJoin did not change the shape of those classes:
http://www.javac.info/jsr166z/jsr166z/forkjoin/Ops.MaxReducer.html.
However, those classes are no longer part of the ParallelArray API set,
replaced by two static methods:
http://gee.cs.oswego.edu/dl/jsr166/dist/extra166ydocs/extra166y/CommonOps.html#maxReducer%28java.util.Comparator%29
.

Cheers,
