This is a review request for the addition of utility methods to java.util.Arrays that provide sorting of arrays in parallel, JEP 103 [1].

A side-note on this: Suitable Object/Comparable versions of DualPivot sort might someday be better fits to the parallel split logic and locality patterns than current Arrays.sort. Vladimir and I discussed this briefly a few years ago, but I don't know if they were ever developed.

Otherwise, on quick glance, despite the now-huge vertical-space usage :-), the updated webrev looks OK to me.
