let me add that the project - it is unfortunately in a somewhat
dormant state due to lack of manpower - can be found here:

Some extensions to the original JSqueak were implemented; mostly they
had to do with colour and font handling. The VM also includes an
optimisation for Large...Integer objects, utilising Java BigIntegers
as shadows.

HPI students once approached a JIT compiler (not finished); the code
is available by request.
