Changing Parallelism in ForkJoinPool

Question

In Java7 ForkJoin pool we can set the parallelism for the pool at the creation time. I could not find any api to change this in the runtime dynamically. Is there a way around to change the parallelism of a ForkJoin pool dynamically?

Answer 1

NO. Although the pool does increase the number of worker threads itself when using join() or managedBlocker(). For more information you can see this article I wrote two years ago.
