Yes, this is what I was referring to. Hotswapping is sort of there
for the jvm. When I use Eclipse, it tries to hotswap. Sometimes it
fails. Sometimes it doesn't. But, referring the criteria in my reply
to Ron's email, would loosing guaranteed hotswapping cause Squeak to
"lose it's soul?" I dunnknow. I'm a newbie. And I don't write
Squeak for a living.
Having read your response to Ron's I think that all you ask for is to
compile Squeak source code into JVM bytecode such that your application
code can access the existing Java API's.
If what you want to do is to access Java objects from Squeak (and vice
versa), you could also consider running the two VMs in parallel, and
setting up a sort of "bridge" to communicate between them.
Having thought over this for a while, I must say that a VM^2 solution
sounds intriguing for folks who are in need of the static j* libraries
(for some reason) but at the same time do not want to miss incremental
development, image based persistence and BlockContexts :)
This might help you even if your eventual goal is to port Squeak to run
in JVM bytecode.
:) Sure.
We did a bridge for Squeak and .NET:

Yes, I'm an admirer of that effort. I know people have asked for Sq/.Net
and (hopefully) are using it (Hans, this is what I was talking about,
perhaps you already have this URL?).

That program is a port of a similar bridge we did for Ruby. In both
cases, we started out running the two VMs in different processes, and
just sending socket-based messages between them; later, we got things
working in a single process. Getting the basics up and running for one
of these things is actually pretty quick, in my experience.
I think that the bridge approach has a lot to recommend it, in that you
retain the advantages of both environments, and can use the regular
production VM of both. (There are of course still some difficulties.)
