JavaXPCOM components

I sent an email to Javier Pedemonte's gmail addr but I haven't
received a response so I figured I'd float my email here and maybe
someone else can help me.

I work on a team that develops a C++ application with a plug-in
extension system. We are looking to write plug-ins in java and one of
the technologies we are investigating is XPCOM. It looks like the
JavaXPCOM code to write Java components is not in the current Mozilla
trunk. Comments on the bugzilla issue suggest that Javier has some
code that works but needs to be integrated with the current trunk. If
we decide to use xpcom, we would be able to spend some time getting
the JavaXPCOM component code updated. I would like to know the status
of this code so I can work up a level of effort. Does the code allow
creation of Java components on an older trunk and just needs updating?
Does it have minimal component functionality but is missing a lot of
features? We have a couple of strong C++ programmers with some minimal
XPCOM knowledge (we've spent about a month getting a trimmed down
version of our app working with XPCOM, C++, and PyXPCOM) so we are not
completely green but would likely need some guidance with the effort.
