Reza,
Thanks for sharing that impression.
Many of those who work for different companies were not involved when the JSRs in question (330 and 299) had to get their act together.
And those who really have so much time are welcome to study the old mail threads between Gavin Kind and Bob Lee and others and what kind of things were said there, until a few members of the JCP EC or Java EE 6 Platform JSR tried to negotiate and stop their fight.
And ultimately allow JSR 299 (CDI 1) to use 330 which was filed later in Java EE 6.
https://jcp.org/en/jsr/detail?id=316 shows, both you (Reza) and I were there at the time. David from Tomitribe and Bill Shannon also was, but almost everyone else is no longer actively involved or interested in Jakarta EE now.
And those working at companies like Red Hat or IBM now probably still went to University or High School between 2008 and 2010.
So please excuse our "seniority" or experience and don't feel offended or upset, if you only joined after Java EE 7 or even Jakarta EE started.
