First time I sent it was from the wrong email address, so it got hung up
in moderation.  I sent it again from my subscribed address.  I'm
guessing someone just moderated the original through.


Anyway, let's address one or two of your points...

I see you writing inflammatory statements about my leadership skills and
I think you're  upset because you think I was questioning the quality of
your work. I understand.  You've put a lot of effort into the codebase.

I feel sorry that you feel that way - it wasn't what I intended.

Apache doesn't recognize any kind of a "project leader" position, and I
don't pretend to hold any such influence over River.  I'm speaking as a
committer and PMC member.  I certainly don't think I "hold the future of
the project in my hands".  If anyone does hold individual control over
the future of the project, then it doesn't qualify as an Apache project,
and we need to remedy that.

Really, what I'm trying to do is answer this question for myself - "Can
I vote +1 on a release based on the trunk?".  There have been a lot of
changes to the trunk code.  Yes, many that I don't understand.  I've
done more management than you thnk.  I don't require that I understand
everything.  That leads me to ask "How can I be confident about a
release?"

The best answer I have is to ask "does it pass the regression tests?". 
But that implies another question - "Do I trust the tests?"  And the
answer to that is "currently, no, because from what I can see there have
also been changes to the tests".

I'm honestly and truly not passing judgement on the quality of the
code.  I honestly don't know if it's good or bad.  I have to confess
that, given that Jini was written as a top-level project at Sun,
sponsored by Bill Joy, when Sun was at the top of its game, and the Jini
project team was a "who's-who" of distributed computing pioneers, the
idea that it's riddled with concurrency bugs surprises me.  But mainly,
I'm still trying to answer that question - "How do I know if it's good?"

Here's what I'm doing:

- I'm attempting to run the tests from "tags/2.2.0" against the "2.2"
branch.  When I have confidence in the "2.2" branch, I'll publish the
results, ask anyone else who's interested to test it, and then call for
a release on "2.2.1"
- After that, the developers need to reach consensus about how to move
forward.

Cheers,

Greg.
