The only nit I find unlucky is that we need to duplicate the TLR code in LockSupport. It looks like we would be better off with the helper class sharing this functionality. I would speculate Doug will contaminate more classes in j.u.c.* with these TLR copy-paste patches, and so we can figure this out once and for all when the dust settles. Yes, exactly so. Maybe someday with module support there will be a nicer way of coping with package-protection problems accessing Thread fields. Until then, because j.u.c has two subpackages (atomic, locks), there's no nice workaround that I know of. -Doug What about copying the Unsafe? A singleton instance that does access checks in the public factory method with usages that cache this instance privately in static fields...
