I haven't looked at your code, but you might have a look at wl
interpreter we discussed some time ago.  The java ffi was quite complete
and quite generic and more importantly, completely automatic, althought
not the fastest due to relying on reflection completely.  There is code
for finding the right method and constructor with matching prototypes
and something similar for fields to get and set them IIRC.
