Scavenging through 9-year-old change-logs is probably
not the best path to resolving confusion :-) There were several
stabs (and back then a highly non-transparent process!) at
conforming to and helping to frame JDK5 VM expectations.

The main point to keep in mind is that the fallback wrapper
(unsafe.cpp  Unsafe_CompareAndSwapLong) does what you
expect (uses the enclosing lock), unless you are in an
uncommon (and possibly non-existent) situation where
you  need/expect something else.
