We-ell, yes. Sort of.

An API to notify Java programs about checkpoint and restore events
seems to me like a weird place to start such a project: it
concentrates on the "how" but not the "what" or the "why".

This project proposal starts with an existing proof-of-concept
implementation. Andrew Dinn's point, I believe, was that solving the
snapshot-and-restore problem in a way that is compatible with the Java
Specification requires thinking about a lot of other things as well.
In order for the API to be meaningful and portable we'd have to
specify a lot of things about what happens when. I don't think that
such an API could be a part of Java before these deep questions were
addressed, as they must be for Project Leyden.
