> See attached project to reproduce.  In short, create an object, update it, and perform a second get on that object (caching is on yes), in that second get in the hibernate trace logging "cached item was locked" is seen.  The operations are done serially and not in parallel, so the cache item should not still be locked as in http://fisheye.jboss.org/browse/Hibernate/core/trunk/core/src/main/java/org/hibernate/cache/ReadWriteCache.java?r=HEAD there is a
> finally {
>    cache.unlock(key);
> }
