Is there a single scenario (other than compatibility with ancient JVMs) where using synchronized is preferable to using a Lock? Can anyone justify using wait or notify over the newer systems?

Is there any algorithm that must use one of them in its implementation?

I see a previous questions that touched on this matter but I would like to take this a little further and actually deprecate them. There are far too many traps and pitfalls and caveats with them that have been ironed out with the new facilities. I just feel it may soon be time to mark them obsolete.
