It is possible, but not yet supported. We should come up with something.
(This would be the equivalent to the JNI "invocation" API.)
I would start by looking at the JvRunMain function in libjava/prims.cc.
That is the glue function that gets invoced on start-up (C main), and
has the basic functionality you need (though you probably have to
change it some).
