As everyone will know, several Oracle-led JSRs (including JMS 2.1) have made little progress this year due to the spec
leads being diverted partly or wholly to work on other things.
At JavaOne last month Linda DeMichel, Java EE joint spec lead, gave an update on progress and plans for Java EE 8.

Linda's presentation proposes a shift in focus for Java EE, to reflect recent developments in the industry, which she
summarised as a "focus on deployment into the cloud", a "focus on microservices", and an "emphasis on more rapid
evolution of applications".
In order to address these changes, and modernise Java EE 8 for "cloud and microservices", she proposed a two-fold approach:
* Adjust the plan for Java EE 8
* Create a plan for, and start work on, Java EE 9
Java EE 8 and JMS 2.1
---------------------
Linda confirmed the plan to complete Java EE 8 in 2017 as originally proposed, but with a number of changes to its
content. These are listed in slides 27 and 28 of her slide deck.
The Java EE 8 JSR and most of its constituent JSRs would continue as originally planned. She proposed that two new
constituent JSRs be added, for health checking and for configuration.
And she proposed to drop three of the existing constituent JSRs: MVC 1.0 (JSR 371), Management 2.0 (JSR 373) ... and JMS
2.1 (JSR 368).
The reason for dropping JMS 2.1 was that JMS was "no longer very relevant in cloud". JMS would continue to be part of
Java EE 8, but at its current version JMS 2.0 rather than at a new version JMS 2.1.
Java EE 9
---------
Linda went on to propose a plan for Java EE 9, which would focus more directly on the new requirements, with work
running in parallel with Java EE 8 and with a release date of 2019. Please see Linda's slides for more details, and if
you'd like to find out more about Java EE 9 I would recommend watching a couple of JavaOne presentations:
Rajiv Mordani, Josh Dorr, Dhiraj Mutreja -- Enterprise Java for the Cloud
https://www.youtube.com/watch?v=t7miysQP7Dg
Josh Dorr, Joe Di Pol, Rajiv Mordani -- Portable Cloud Applications with Java EE
https://www.youtube.com/watch?v=nCqVSf5v37s
There are two presentations because there was too much material to fit into a single presentation. They include some
proposals for a new "eventing" JSR in Java EE 9 which I suspect will be of particular interest.
Your views
----------
Your views on all of these proposals are invited.
You can make comments on proposal to drop JMS 2.1 from Java EE 8 here (users_at_jms-spec.java.net) or you can reach a wider
audience by sending them to the Java EE users mailing list (users_at_javaee-spec.java.net). You can sign up to the latter
at
https://java.net/projects/javaee-spec/lists
Comments on the proposals for Java EE 9 (including the "eventing" proposals) should be made to the Java EE users mailing
list.
In addition, the Java EE spec leads have launched a new Java EE community survey. Please do take part and give your
views on the future of Java EE. This is at
http://glassfish.org/survey . The survey closes on 21 Oct 2016. This will be
followed by a second survey that allows people to prioritise the top items from the first survey.
