Of course the good thing is -- once code is formulated in terms of
lambda predicates, switching parallelism engines is a smaller matter.
So if fork-join is full of it, use a different one. Sure, it will take
a bit of a code change to avoid the default parallel streams, but
nothing near what it took to change from hard-wired, procedural,
data-traversal-and-logic-all-in-one code.
That's not to defend fork-join -- just rejoicing that its far easier to
switch parallelism algorithms with lambdas.

Very interesting article. While I can't claim to understand it all in
detail, I am not too surprised (this is Java after all). How can one
expect a coherent, simple and pragmatic parallel programming model, by
a CS professor isolated at his university?!
This is in stark contrast to C#, where the elephant is chopped up and
digested in pragmatic pieces by a team of designers meeting 3 times a
week, responsible for the programming model as a whole (one does not
need to be a CS major to use PLINQ, Parallel.For etc.).
Bummer :/

I've added a new article just for Java8:
