Thanks for the praise, and giving my arguments on that forum your consideration.
FWIW, I am also one the folks who helped getting Apache Harmony going, so I am
trying in a lot of ways to help fix the problems I see with Java, in different

That's an interesting idea, but unfortunately, it can't be done in an
implementation that wants to be certified as Java compatible, like Harmony,
since the VM + class library that you ship needs to be certified as compatible,
not the VM + class library + something you download on demand from some server
if you have a network connection around. The fundamental problem with the idea
is that you end up effectively subsetting J2SE, and the current rules do not
allow for that, a J2SE implementation always needs to behave as one, even
without a network connection. :)

Welcome on board, and have fun.
