Well, I'd hate to lose the Base's functionality, for sure.  But IMO
someone has to eventually look into making Base JRE independent anyway
since it's a core application.

As for several Java extensions that we ship with go-oo, NLP Solver and
Watch Window *could* be re-written in C++ with some moderate effort, as
they don't rely too much on Java API.  However, GoodDoc extension uses
Swing for its GUI, which is hard to replicate without Java.
