Probably not; it's an effort to write an LGPL'ed version of Sun's
APIs, so no VM work is required. (http://www.classpath.org)
BTW, another Java VM is Japhar (www.japhar.org). I can't say which VM
is more complete, or more commonly used. And can either of them
handle JPython at this point?
(It's surprising how anemic the free Java projects are. Classpath's
most recent snapshot release is dated 1999-02-06, over a year ago; the
last Kaffe release was in October, and the last Japaher release in
March 1999. I would think that a Java VM + API, because the APIs are
so large and can be developed incrementally, would be really suited to
frequent smaller releases.)
