J2EE, Java EE, Jakarta EE, MicroProfile - and The Release Cadence

J2EE was released every 2 years, Java EE every 3-4 years:

  1. J2EE 1.2 (December 12, 1999)
  2. J2EE 1.3 (September 24, 2001) (2 years)
  3. J2EE 1.4 (November 11, 2003) (2 years)
  4. Java EE 5 (May 11, 2006) (3 years)
  5. Java EE 6 (December 10, 2009) (3 years)
  6. Java EE 7 (May 28, 2013) (4 years)
  7. Java EE 8 (August 31, 2017) (4 years)
[from: https://en.wikipedia.org/wiki/Java_Platform,_Enterprise_Edition#cite_note-4]

With a Jakarta EE release in 2019 (status), the release cadence would come back to 2-years cycle of J2EE days. A Jakarta EE release in 2020 would be still aligned with the Java EE cadence. However: Jakarta EE plans to have more frequent releases.

All major application servers are already supporting both: Java EE 8 and MicroProfile at the same time (see matrix).

MicroProfile and most application servers are already released quarterly. Now you can write your ThinWAR applications against the stable Java EE 8 API and enjoy new MicroProfile features several times a year.

See you at Web, MicroProfile and Java EE Workshops at Munich Airport, Terminal 2 or Virtual Dedicated Workshops / consulting. Is Munich's airport too far? Learn from home: airhacks.io.

NEW: Online Workhop Effective WebApps without Frameworks is also coming to: MUC Airport.

Airport MUC workshops: Web (SPA, PWAs, Offline, Desktop, Mobile) Applications Essentials and Effective Web Applications. No migrations. #usetheplatform

"All major application servers are already supporting both: Java EE 8 and MicroProfile at the same time"

I also expected Jboss EAP and Websphere Traditional to support Java EE8 but, to this date, this is not the case (Please correct me)

And I'm not aware of any plan for this to happen.
