I don't think he has a close BDFL-style involvement with the Java SDK or standard library. From what I can observe, Java is, and has been, committee-driven since about 2000.

And Gosling is too expensive to write code. His time is much better used in conferences, motivating developers.

I don't remember having seen his name for a long time in any technical discussion or decision involving Java, besides Closures, where he co-authored the BGGA proposal. Although it appears that Gafter and Bracha put more work in that one. Even then he did not apparently have enough say on the matter to make his blessed proposal official. His main role seems to be an evangelist for the platform and perhaps researcher for some more involved areas, like real-time systems and numerical processing, AFAICT from his blog posts.
