Ok, excuse that mail.
Jay R. Ashworth:
Because the problem is *not* "shouldn't some things which are now written in Java be written in JS, etc, instead?", it's "There are indisputably useful things which can *only* be written in Java for the deployment environment being discussed", and he didn't solve that worth a damn, alas.
I wasn't trying to prove it. It should be addressed by Andreas, who wants them. I pointed the example didn't need Java at all, but Rob opined it was a trivial implementation (Andreas probably disagreed). I agree it doesn't probe, but i'm not pushing for java :-) They do exist, can some of them be needed on a wmf project? Don't know. Show me one to decide ;-) Or maybe it could be done in both but it's coded 200% faster in java, who knows...
