Is “Java Concurrency In Practice” still valid?

Question

Is Java Concurrency in Practice still valid? I am wondering whether the ideas, concepts, and implementation described in the book are still compliant with the latest Java versions.

I ask because the latest edition was done in 2006.

Answer 1

Yes, it's nevertheless efficient in my understanding. There isn't a big difference in this area from 6 to 7. Fork-join is a unique feature, which is very fitting for the divide-and-conquer type of dilemma. But all the actual essence inside the book, such as synchronization, volatile, servlet, are yet very valid.
