As part of JEP 155 (Concurrency Updates) we are proposing to add StampedLock. A capability-based lock with three modes for controlling read/write access.

Javadoc: http://cr.openjdk.java.net/~chegar/8005697/ver.00/javadoc/StampedLock.html (some external links are not working in this online version) Webrev: http://cr.openjdk.java.net/~chegar/8005697/ver.00/webrev/webrev/

Martin Buchholz pointed out a javadoc warning. I also noticed that I had failed to include the simple toString-based informal debug/monitoring aids that we've been doing for synchronizers. Sorry. Now added. For example, printing a lock twice during a test: java.util.concurrent.locks.StampedLock at 29178281[Read-locks:13] ... java.util.concurrent.locks.StampedLock at 29178281[Unlocked]
