> DFSUtil contains a "shuffle" routine that shuffles arrays. With a little
> wrapping, Java Collections class can shuffle. This code is superfluous and
> undocumented. The method returns an array, though it does not specify if it
> returns the same array or a new, copy, array of shuffled items.
> It is only used in one place, so it is better to simply remove and substitute
> this implementation with the java Collections implementation.
