Right. It would be even more desirable if you can find changes that
make cmd work out of the box, such as introducing a readline module in
Jython.

Just grep the standard library for "java".

What do you mean by registry file? How is that related to the cmd.py
changes?

In general, you give the source of configuration information when
accessing it, e.g. os.environ, or _winreg. So if you want to read Java
properties, you should specify them explicitly. You couldn't confuse
them with environment names, anyway, since they have completely
different conventions.
