The JMS 2.0 Public Draft is now published on the JCP website.
http://jcpdev.us.oracle.com/aboutJava/communityprocess/pr/jsr343/index.html
The review period will end on Monday 4th February 2013.
I have created a wiki page which contains information about the public
draft:
http://java.net/projects/jms-spec/pages/JMS20PublicDraft
(this is referenced from the top of jms-spec.java.net). Please invite
your colleagues to visit this page.
As I mentioned before, PLEASE CONTINUE TO MAKE COMMENTS. We are allowed
to submit an updated version of the draft up until two days before the
end of the review period, and I intend to do so.
The above wiki page also contains information about where you can find
the latest build of the reference implementation. Almost all the
features are now implemented (and only bugs remain), so how is an ideal
time for you to try out JMS 2.0 in practice.
