Seeing as this was raised in the jre5 thread: > java.util.concurrent > java.util.concurrent.atomic > java.util.concurrent.locks
Note that the java.util.concurrent implementation, as defined and implemented by the JSR-166 is freely available for download: /* * Written by Doug Lea with assistance from members of JCP JSR-166 * Expert Group and released to the public domain, as explained at * http://creativecommons.org/licenses/publicdomain */ Follow links to the CVS repository: http://gee.cs.oswego.edu/dl/concurrency-interest/index.html These API's rely in part on some native VM support - particularly for atomics and low-level lock support. Atomics in particular only reach their full potential if the JIT/AOT compiler knows what to do with them and can "intrinsify" their use.
