I'm still not sure what your switch really solves in real use (outside
of your app).  It looks like a simple proxy object.

The part that won't work is the bit about a company "negotiating with
Javasoft" and integrating a special whatsit.  The only versions of JDK
1.2 that had the "old names" were beta and just downright crud.  You'd
never keep your customers if you deployed against that JDK.

The other part would be convincing any company to re-write a piece of
their product (like a deployment wizard) to handle a special case like
this when there are no real benefits to the majority of the folks they
sell to.  I'd be pretty hard pressed to convince someone that
deploying against a special, non-shipping JDK and JFC, one you can't
get anymore was better then adding support for some feature that is in
the shipping Java world.

If you see something that looks like an opinion up there,
it's mine and mine alone.

Mail sent to me from the newsgroups won't bounce but will
be ignored.  If I have time, I'll respond, but you  have
a better chance if you confine your posts to the newsgroups
