As promised (several months ago) an initial version of
class jsr166e.StampedLock is now available. This is
a combined write/read/optimistic lock that has some nice
properties and good performance. For description, see
And see the usual links from
for jsr166e jars and sources.

Reports about usage experiences would be very welcome!

SequenceLock is now moved to "jsr166e.extra" and no longer
a candidate for inclusion in JDK8.
