Cen,
It's hard to get a particular statement
or desire from your many points.
I get a "Jakarta EE bad, Microprofile
cool" sentiment, but that is not new.
Without Java EE there would be neither
Spring nor Microprofile.
MP is a lot like Spring, but it is still
in a very early stage, comparable to Spring 1.2 rather
than 2.0, especially when you look at true adoption or
answers to surveys.
Plus Jakarta EE 8 is 1 or sometimes 2
steps ahead of Microprofile specs that have not been
upgraded to use Java EE 8 yet. It's a "Dependency
Hell" because some need CDI 1.2, others already
require 2.x
A large number of Spring projects
already uses the new Jakarta EE specs. ;-D
You discovered that EclipseLink has more
than Bugzilla and the more recent important ones
should be there. Bugzilla has many, but Hibernate ORM
alone got 2861 open issues in its JIRA, so does that
mean you consider both abandonware? ;-)
The "incremental vs. Big bang"
discussion was about refactoring from javax to jakarta
namespaces and not how many new specs Jakarta EE 9, 10
or 11 might include. For 8 everything was put in a new
Maven Groupid but that is not the biggest effort.
Think of JPA alone there are many XML
files referring to Java or JCP.
Whether all get changed with Jakarta EE
9 or only the most commonly used remains to be seen.
