This book is not derived from Concurrent Programming in Java, and it takes an entirely different approach. Where Concurrent Programming in Java is an encyclopaedia of "All Things Concurrency", Java Concurrency in Practice is more of a practical tutorial, addressing design principles, mental models, and practical rules that should make it easier to write safe and performant concurrent programs. It also covers the new concurrency features in Java 5.0 and Java 6.
That said, you can bet that many of the things on Doug's "Things to say in CPJ/3e" list were addressed in some way in this book. (Number one on this list is, of course, how to use the classes in the java.util.concurrent packages.)
