Another round of improvements to ForkJoin framework is
now available in the usual places (see below). The main
change is an overhaul to core control that better avoids
creating or restarting more threads than needed. You'll
probably see better overall performance too.
Also, exceptions stemming from user errors are now
more informative.

Please try these out let us know about any problems.

file path.)
