This was a great suggestion; thanks!

I'm not sure there is enough of an identifiable community there
to decode this. Some people think they need Mersenne Twister,
with 4096bit state and 2^4096 periodicity. But that would make
a poor candidate for JDK. On the other side, there are people
who most care about cost and are happy with a generator that
is at least not obviously too regular, but we don't supply those
either. The 90+% in between are likely to be happy that JDK8
provides something both cheaper and better than java.util.Random
to use when it applies.
