Hardly:
http://icedtea.classpath.org/mirror/git/classpath/classpath/ (commits 6 days ago)
http://developer.classpath.org/pipermail/classpath/2012-March/thread.html (active discussion)
How is this dead? There's less than there was, yes, but that's because Sun (now Oracle)
have largely succeeded in persuading people to switch to their less-open OpenJDK project.
We always had problems generating interest before OpenJDK (quite a lot of people seemed happy
to put up with the proprietary but gratis JDK downloads from Sun). Having a more complete
open source project is obviously going to sway those who want a full JDK now (notably distros), but
there will be those still interested in the intellectual challenge of producing a JDK themselves.
I think there are clear issues with having a single implementation of a platform; it leads to
confusion between what is part of the specification and what is merely an artefact of implementation,
an issue we've hit many times in developing GNU Classpath.

I can't comment much on Harmony, but it always seemed to have less of a user-driven community than
Classpath to begin with and has officially been put in the 'attic' as far as I'm aware.

It would help if you did a little research before making such claims.

Depends on what you want to do. It doesn't have CNI.
