Re: [jakarta.ee-community] Thoughts on JakartaEE

I don't think "Jakarta EE bad, Microprofile cool" is a fair statement, it's rather that MP complements it quite well and can't exist without JakartaEE which solves a huge chunk of the scope for MP. Spring is a fair comparison but they kind of do their own thing.

Very well said, Cen! At Code One, I did a talk on the comparison of Spring and MicroProfile. The slides can be found here. IBM bluecomputing team did an experiment on converting microservices written originally using Spring boot to MicroProfile. A series blogs on this experiement can be found here.
I am biased towards "change it all" approach for the simple fact that we deploy microservices. We can take a single microservice, port it to new namespace and redeploy the docker container. Repeat 30 times as schedule permits. Once you port a few of them you already learn all the pitfalls for next port.
Please share your view on the thread [jakartaee-platform-dev] Transitioning Jakarta EE to the jakarta namespace. 
I think there was also an idea floating around to prune the list first so that we can stablise some specs that hardly have a reason to be updated or moved-away technologies. If changing one spec involving 90% other spec changes, then it is not much difference between big bang and incremental. Personally, I also prefer incremental as there is not much business value to change something for no business need. However, for runtime, it is important to cope with old namespace javax and new namespace jakarta, no matter which approach is chosen. It is an implementation detail.

I have a love/hate relationship with EL and Hibernate because they are both good implementations with a few very annoying bugs, when weighted with annoyance factor, it tends to lean towards EL being slightly better so I am strictly on EL these days. :)

I am a bit confused here. EL is part of Java EE spec while hibernate is an implementation. When you say EL, do you mean some implementation instead of _expression_ Language?
Thanks

It is hard to formulate a particular statement for me because of the scope of the problem so those are merely my observations with no strong opinion.

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.

+1 taking into account what cen says for me now have more much sense the incremental approach than try to migrate everything at once.

IMHO

+1. I like what you wrote Cen. It does matches my perspective as well.
