Thanks for reaching out to Pivotal/Google. You know best, Google may be a
bit tricky considering the lawsuit.

And please cool down about non-responsive or inactive peopple in the JCP or
elsewhere. As you know best (though you are not the primary rep for LJC
there any more), the JSR 364 EG EC and other JCP.next initiatives were keen
to get people involved, but we don't want "Vanity Members" who just claim
they are on a list or get their "pin stripe" full of JSR or other Open
Source "memberships" without ever contributing more than to say "Hello" or
"Goodbye" in a mailing list. Regardless of his or Interface
21's/SpringSource's contribtion to the larger Java ecosystem, the former Co
Spec Lead or JSR 330 Rod Johnson was exactly that case (I personally
whitnessed his "15 min. of Fame" in a single EC F2F where he then vanished
and was never seen)
And especially in JSR 354 Crazy Bob has been equally invisible. Which is
why Anatole wanted to have a word with him about still being on the EG or

We need people like Antoine who try to get things done now, not
"filibusters" or some "bust" in a "Hall of Fame" (well, to some extent
that's what the "Rock Stars" are for[?]), neither in this JSR nor others.
There could be other roles for them from "Observer" to "Contributor" (if
JSR 364 concludes) so please try your best to get 364 or 358 out, but spare
this here.
