Another Great Divide

OpenJDK to add closures sub-project

As I've noted in blogs over the last few months, all the major closure proposals are backed up with implementations, so it's possible for interested developers to take each out for a spin. In fact, to save you a few minutes of Googling, here are links to blog entries introducing each implementation:

Interestingly, Stephen and Mark acknowledge that their implementations are based off the OpenJDK project's emerging Java 7 codebase, while Neal's instead requires that you have JDK 6 versions of java and javac on your path.

And the coupling to OpenJDK brings us to an interesting item in today's news, the announcement of an official project to bring the BGGA implementation to OpenJDK.

Following a unanimous vote by members of the Compiler Group, the OpenJDK project has approved a closures project. The project was proposed by and will be led by Neal. Its stated goal is "to produce a feature-complete prototype of the Java bytecode compiler (javac) for the draft BGGA Closures specification", and will serve as the workspace for the closures effort in the OpenJDK Community Innovators' Challenge.

So does this give BGGA a sort of incumbency advantage over the other proposals, given its status as an official part of OpenJDK? Let's not jump to conclusions: the others have implementations already based on OpenJDK, after all, and we won't know which (if any) are in Java 7 until the JCP takes up the issue of a Java 7 contents JSR, which is still a ways off.


Also in Java Today,

Eduardo Pelegri-Llopart has posted some Updated GlassFish Roadmaps. "Anybody that has been in the software industry for any time knows that roadmaps are always "work in progress".
With that caveat, here are the latest news:

GFv3 TP2 is a "Technology Preview" release; we will provide a sneak peek at
CommunityOne
and will be demoed at
JavaOne.

The latest edition, issue 166, of the JavaTools Community Newsletter is out, with a note about the recently-concluded FISL conference, tool-related news from around the web, news from projects, announcements of new projects in the community, and a Tool Tip on facilitating access to your open source projects at java.net.

Oh, come on. Pull the other one. Everyone who watched the closure charade knows very well that (a) closures for Java 7 are already a done deal, and (b) Mr. Gafter is Sun's closure darling.

I just wish Sun would finally be honest and reveal what has already been decided, instead of taking us for a ride.
