This is indeed a very important branding, marketing, and strategic consideration. What we observe is that while Jakarta EE adoption and usage is not stellar, MicroProfile adoption and usage fares even worse: https://trends.google.com/trends/explore?date=2016-01-21%202025-02-21&q=Jakarta%20EE,MicroProfile&hl=en. These have been the trends for some time now. It's not surprising when customer express the preferences on this matter to us.

As Steve mentioned, the adoption and true certification of MP is merely a fraction of Jakarta EE.The most recent MP versions only got certified by one or two products, before that MP 6 had 4 compatible products according to Steve. Jakarta EE lists around 20 product by almost the same number of vendors. Not all may have certified against Jakarta EE 10, but in general the number of compatible implementations is higher. And let's not forget, MP as well as Spring also implements some of Jakarta EE, so that multiplies the usage drastically.

Hi,
Can you please clarify which standards MicroProfile Config cannot meet?
Also, why is there an assumption that MP Config wouldn’t accept some sort of release alignment? MP projects are free to release anytime they want.
Cheers,Roberto

Hi,
Yes, MP decided on the pull model. That means that the decision is solely on Jakarta EE, with the pull model, MicroProfile has decided they don't care about EE.
Copying/forking MP Config is not the only option, even with the pull model. Even with this model, Jakarta EE can depend on MP Config, or a core part of it (without CDI). But I doubt that this is the way to go in reality. MP Config most probably cann't meet the standards of Jakarta EE. Another problem is that MP and EE have different release cycles, and, even if EE depended only on a core MP Config part, releases of MP, MP Config Core, and EE would need to be synchronized. I doubt that the MP would accept that.
For the arguments above, the only reasonable options I see, are:
- MP Config participates in this process and splits to core part and CDI part, so that the core part can be moved to Jakarta EE Core Profile without package changes
- Jakarta EE copies the core part of MP config under the jakarta package prefix and adds it to the Core Profile. Jakarta EE can introduce a new CDI Config integration spec, or the existing CDI spec can specify integration in the non-lite part, which is not part of EE Core Profile. This could still cause conflicts for implementations that provide both MP and EE, but we can hardly do anything about it
- Jakarta EE will not care about MP Config and will introduce its own API. This option makes sense only if all other options fail. We tried that already and haven't delivered in more than 2 years.
This basically boils down to extracting core parts of MP Config, and the question is whether to keep the package names or introduce jakarta package names, and whether MP helps and splits the MP Config spec or not. The third option is probably the least desired right now.
Are any other options on the table?

To be honest the whole thing is a mess that should have been sorted out years ago. As one of the 4 vendors that actually has a compatible implementation of Microprofile 6 and above the two WG should have merged years ago with innovation occurring in Jakarta ee as standalone specs then maturity being signalled by adoption into a platform spec.
On this particular point as Kenji stated MicroProfile explicitly voted on the pull model 5 years ago!!!! https://docs.google.com/document/d/1VQ5cvzhVhKYr27FKC1tVmf081eGLSNiuX-dhQ2BxItc/edit?pli=1&tab=t.0#heading=h.7e20q7f70ond which includes the explanatory text
"Downstream consumers will probably require a fork (with changing package names) to meet the downstream projects requirements."
This should not be controversial as it is rehashed continually.
While we have the same debates the market does not care and moves on.

I strongly disagree with forking MP Config to Jakarta with namespace changes. This introduces unnecessary headaches and namespace clashes in the IDEs. Why cannot Jakarta EE adopt MicroProfile Config as it is and job done? No more hassle.
The namespace update is purely artificial and causes too many headaches and version matching. In order to continue the forking and namespace changes, can anyone show me the rule of Jakarta not allowing the use of MicroProfile specs first?Emily

Kito/all,
Thanks for forwarding this, although the quote of quotes of quotes makes it very hard to read.
I fully agree with Otavio's message that both are developed under the Eclipse Foundation, and users of a product don't really care, if it was developed in repository A or B.
However, what Roberto outlined earlier about continuous copying between MP Config and Jakarta Config makes absolutely no sense.

MicroProfile consumes Jakarta EE, so there is no MP application or platform without a Jakarta EE platform, at the very least the Core Profile. So Jakarta Config is expected to be available in every profile. If the MP Config API was to co-exist with Jakarta Config forever, then applications would have to exclude one of them from their build system, otherwise they risk confusion or even mixing them in the same project with unforseen and unpredictable consequences. Especially if a Jakarta EE application using Jakarta Config API also wanted to use certain MP features like OpenTelemetry, Health, etc. internally configured via MP Config, but potentially even a different version of the API, if e.g. MP 8.1 used a new version of MP Config while Jakarta EE was still on 12 or 13 based on an older MP Config API.
If the API is a drop-in-replacement then nothing keeps the MP projects from using the Jakarta one after the next release. And it does not really matter, if it was maintained in https://github.com/jakartaee/config orOtherwise everyone, most importantly developers and users of both MP and Jakarta EE would face a "config hell".

I think that makes a lot of sense. Each spec just says what it needs from a "Configuration Provider" and that provider would be either MP Config or Jakarta Config.With all that, I share the same sentiment with Reza. I always hoped that MP would tend to donate APIs to Jakarta after they become stable, and then completely rely on the Jakarta version of the API.I agree with this sentiment as well...We need to also keep in mind the perspective of the end users... they want a "normal" configuration setup that "just works" with all of the different parts of the app. And it would be confusing to have two different namespaces with the same classes. It's also confusing for the end user to have two different Config specifications, even if they're roughly the same.___

I am sure Ed and/or Jared will respond with their own thoughts - in the meantime let me share my two cents, including on some of the broader technical intricacies.First a purely personal opinion independent of Microsoft. These are some of the intricacies of managing two platforms run by two separate working groups that in practice need to co-exist closely. It's the reason some of us espoused the hope that common dependencies and possible sources of colliding resources to manage would only be in one direction with the Jakarta EE Core Profile being keenly mindful of the needs of both MicroProfile as well as the other Jakarta EE Profiles (and hopefully in some distant future other non-Eclipse Foundation platforms that also depend on a stable/high-quality/minimal Core Profile). The hope would have been that platforms such as MicroProfile would deprecate APIs that are effectively standardized onto the shared space of the Core Profile.Setting aside the above purely personal opinion, if MicroProfile is very averse to supporting both Jakarta Config and MicroProfile Config, I don't think it's too hard to just keep Config out of the Core Profile including the small handful of Jakarta EE APIs there (via spec profiles if needed). The major customer pain point is needing to configure the data/external infrastructure related Jakarta EE technologies using old style embedded XML or Java, which are mostly not in the Core Profile anyway.

Is this correct?

I plan to bring this up in the Jakarta EE Steering Committee. The technical debate aside, I think there are also process and branding/IP considerations here. For one, it's important to track down what the existing consensus had been in Jakarta EE WG/Jakarta Config with regards to namespace. A sanity check from the perspective of branding/IP is also in order as these are in reality two different working groups.I agree that the most prudent approach is avoiding needlessly introducing mutual inter-dependencies. Both MicroProfile and Jakarta EE should be able to independently evolve their configuration approaches when needed. Separate namespaces with APIs synced manually/selectively when needed does that well.

A technical problem regarding introducing circular dependencies.Yes, the issue is that MP Config is dependent on CDI. This has been discussed many times, and I believe MP is open to make the necessary adjustments and removing that restriction. In the previous Jakarta Config initiative, that was already a goal. One of the things I’ve been advocating is for MP Config (or any other Config specification), to work standalone without any other dependency. This would allow any Java project to consume it without requiring the use of the platform. As for the CDI, that can be an addendum to the specification or even be integrated into CDI itself.+1. We can rework MP Config to use the CDI approach by dividing MP Config to MP Config Core and MP Config full, where MP Config Core will just have the spi part while the other part will include CDI. In this way, Jakarta can simply include MP Config Core in the Jakarta Core profile. With this, I think Jakarta can simply include MP Config Core with the need of having Jakarta Config. With this approach, renaming microprofile-config.properties to application.properties is not mandatory as the package namespace would contain microprofile.2. A non-technical problem where Jakarta specs may not makedependencies on MicroProfile artifacts.Can we clarify what the problem is exactly? Is this something that can be worked out?What I’m trying to understand is if we could work on the technical and non-technical issues that prevent Jakarta from adopting MP as is (without copying and renaming packages), and assuming we can have those fixed, would Jakarta be able to use it as a regular dependency?To my best knowledge, there was no restriction for Jakarta to use MP as long as the MP spec do not depend on Jakarta. If MP Config Core is consumed by Jakarta, there would be no circular dependency.
