The Java Streams stuff is great for stream-based data parallelism. It is a
huge improvement over what was in JSR166extra. Part of the work is to decide
whether to preserve any of the old GPars API implemented with Streams or just
to delete it and have Groovy users use Streams. In fact we can have both but
only if someone does it. I tool a view to remove, but some have put in partial
replacements, it's a WIP that needs completing or removing.

However GPars has much more than Java offers: actors, active objects, CSP,
dataflow, to name some major bits. This stuff needs updating for JDK8 – to
remove lots of redundant stuff that was in there because JDK6 and JDK7. Also
the tests need a big review to ensure the GPars needed and used by people is
actually tested.

As far as I am aware there are other actor systems, and some dataflow systems,
but nothings as complete as GPars for offering these forms of parallelism.
