To join a mailing list discussing this JSR, go to: http://altair.cs.oswego.edu/mailman/listinfo/concurrency-interest. (Archived postings may also be found at MarkMail's searchable archives.)
While JSR166 has completed and is a now final approved JCP spec, the expert group remains involved in incremental improvements and changes to the java.util.concurrent package and related classes and packages.
The current versions of JSR166 classes, including updates for JDK6 and JDK7, can be found in:
New classes that may appear in JDK8. These require Java7 to compile and run. The subpackage jsr166e.extra includes classes relying on jsr166e that are not currently targeted for package java.util.concurrent in JDK8 but may be released separately.
New classes targeted to appear in JDK7. These require Java6 to compile and run.
There is also a wiki containing additional documentation, notes, advice, examples, and so on for these classes that you are welcome to contribute to. (It is currently out of date with respect to jsr166y vs extra166y packaging and APIs.)
Preliminary versions of classes that build upon those targeted for JDK7, but are not planned for inclusion. These require Java6 to compile and run.
Preliminary versions of Deques (double-ended queues) and Navigable collections (concurrent sorted maps and sets) that appear in JDK6 are separately available as package jsr166x, which can be used with any Java5 JVM:
For the official JSR166 proposal see the JCP web site.
The initial contents of JSR166 were released as part of J2SE 5.0 ("Tiger") , mostly in new package java.util.concurrent.
Sources for all classes originated by the JSR166 group are released to the public domain, as described at http://creativecommons.org/licenses/publicdomain. This includes all code in java.util.concurrent and its subpackages (except CopyOnWriteArrayList), as well as java.util classes Deque, NavigableMap, NavigableSet, Queue, AbstractQueue, PriorityQueue, and ArrayDeque. Additionally, the JSR166 effort included modifications of openjdk versions of a few other java.util classes including TreeMap, AbstractMap, LinkedList, and Collections, which carry GPL+Classpath exception licenses.
Many of our internal functionality and performance tests are also in the CVS repository, at http://gee.cs.oswego.edu/cgi-bin/viewcvs.cgi/jsr166/src/test/loops/. Other (overlapping) sets of tests designed for use in openjdk testing may be found in http://gee.cs.oswego.edu/cgi-bin/viewcvs.cgi/jsr166/src/test/tck/ and http://gee.cs.oswego.edu/cgi-bin/viewcvs.cgi/jsr166/src/test/jtreg/. Some are poorly documented, and some target only specific functionality or performance issues so may not be useful indicators. (A unix "runscript" is available to run most in "loops"). Still they may be useful for tracking changes, comparing VMs and VM options, or exploring alternative implementations.
The book Java Concurrency in Practice by Brian Goetz, with Tim Peierls, Joshua Bloch, Joseph Bowbeer, David Holmes, Doug Lea. Addison-Wesley, 2006 describes use of java.util.concurrent.
Slides from the JavaOne Collections Connection BoF (PDF) (PPT) describe Tiger and Mustang collections features, including concurrent collections.
There is a a case study report about the JCP process used in JSR166.
There is a technical paper on the JSR166 synchronizer framework appearing in the 2004 PODC CSJP Workshop.
Expert group member Brian Goetz has written several on-line articles about java.util.concurrent features, as listed at his publications page.
There are some out-of-date but mostly still accurate slides on highlights of JSR-166.
The initial contributing members of the JSR166 expert group are Josh Bloch, Joe Bowbeer, Brian Goetz, David Holmes, Doug Lea (spec lead), and Tim Peierls. Martin Buchholz and Bill Scherer joined as members in maintenance and extension efforts. Others contributing notable guidance and expertise include Dave Dice (Sun), Cliff Click (Azul), Steve Dever (Sun), and Bill Pugh (UMd). Thanks also to the many other people contributing ideas, reviewing APIs and code, and testing out pre-releases.
