JSR-166 and the JCIP book

One of the best toolkit today for concurrent programming is the JSR-166 API in Java SE 5 and the related mailing list, concurrency-interest, and book, Java Concurrency In Practice (JCIP).

Nevertheless, the use of these tools show that it is still very difficult to build concurrent applications and that we need even better tools, such as a new programming language and/or development tools.

And until then, JSR-166, with the great support from Doug Lea and his team, are the best that we have.
