The ForkJoin implementation in the 166 repository:

http://gee.cs.oswego.edu/cgi-bin/viewcvs.cgi/jsr166/src/main/java/util/concurrent/ForkJoinPool.java?sortby=date&view=log
http://gee.cs.oswego.edu/cgi-bin/viewcvs.cgi/jsr166/src/main/java/util/concurrent/ForkJoinTask.java?sortby=date&view=log
http://gee.cs.oswego.edu/cgi-bin/viewcvs.cgi/jsr166/src/main/java/util/concurrent/ForkJoinWorkerThread.java?sortby=date&view=log

has been updated with improved thread throttling behaviour:

http://cs.oswego.edu/pipermail/concurrency-interest/2014-July/012836.html

The implementation in jdk 9 (and preferably 8u40) should be updated accordingly.
