The best forum is unclear right at this point. At the moment JSR-335 has 
just been proposed, to add closures, and it hopes to include 
enhancements to core APIs such as collections.

Exactly what form that will take will be discussed by the expert group 
and I would expect they will establish some kind of forum for public 
discussion and comments.

So hold that thought.
