You can read about most of it here . Basically all but one has joined up behind a proposal for a JSR about adding closures to Java.

Since the authors of all three current major closure proposals, except notably my personal coding hero Joshua Bloch (author of the Java bible - Effective Java), seem to be backing this JSR. Chances are very high that you will be directly affected by the outcome of this JSR, so speak up and praise the lord for this proposal to Pimp My Java.

Personally I wonder where the solution will land. At CICE (fixing anonymous inner classes with a better syntax), BGGA (adding a construct that basically let you add new language constructs to Java) or FCM (somewhere in between)? I found a good post by "Crazy Bob", with a nice graph, though it doesn't include FCM.

The fact that Joshua Bloch is missing from the list is peculiar. It might just be because of legal reasons within Google and have no real meaning but it is interesting nevertheless. Josh has IMO always been extremely clear sighted about the mechanisms behind good coding and good language constructs, so his position might be interesting. Let's see how that evolves.
