I started implementing this.
The appended patch just scratches the surface. I got a bit depressed
writing this patch -- there are that many stubs. Ugh :-(
I'll hold off committing this until sometime tomorrow. If someone
objects to it going in, they should speak up.
This is going to crush our JAPI scores. Bitter medicine is good for
you :-)
Ways to find stubs:
* Search for 'stub'... but this gives false positives from things
like corba and rmi
* Use Eclipse and search for references to the Error constructors.
This finds a good number but there are a couple places where we
throw Error on purpose (and also this picks up the constructors of
all the subclasses of Error :-)
* Search for 'not implemented' (surprisingly, 'unimplemented' yields
very few hits)
