Re: [jakarta.ee-community] Compatibility Matrix with OpenJDK

[Edwin Derks <ederks85@xxxxxxxxx>]

Hi Werner,

I see what you mean, on the Proof of Compatibility page there is a notion of which Java SE version has been used for compatibility. Although this is the answer to the compatibility question, is it apparent and sufficient enough for people to look there? It wasn't for me so I'm wondering if it is for others. Also meaning that if for any arbitrary server Java SE 8 is mentioned there, does it mean that it's not or also Java SE 11 compliant? So I think there's still value if we can provide an overview/matrix for this. What do you guys think?

That's not really precise because Jakarta EE although it may often be used on Linux environments must be platform independent, and not every OS works with Docker, so I would not show that on the Jakarta EE page.

Vendors are free to do that, if they feel it's beneficial, but I don't think it is useful for the Jakarta EE site.

I have an assumption that every vendor has its own docker container repo nowadays, so potentially it's possible to get all tags and build the matrix. Please let me know if this assumption is wrong. We plan to implement related automation for internal needs to get rid of some manual work while preparing Jakarate EE container runtimes. We can share this info if others believe it might be useful for them.

That's already there although it may be OpenJDK 8 for Jakarta EE 8 in all cases.

You have to click on the "Proof of Compatibility" page where you see which version was used to run the test.

With 2 major JDK releases it's quite impossible IMO to put that with each product on the first page, plus each vendor should have space for that e.g. under the "download" page.

Each Jakarta EE version has a minimum Java version it supports and from Jakarta EE 9 on there's also a maximum version I expect that can be supported especially by the TCK. 

It's up to each vendor to chose which JDK they use within that range for the compatibility test.

Hi all,

I also think this is valuable. It is something that I would like to know when I put my developer hat on. Would this be a nice addition to every certified application server listed on https://jakarta.ee/compatibility?

Hi,

I don't think so. Would not be a bad idea to add this.

For my own product that attempts to implement Jakarta EE APIs (https://piranha.cloud) the latest release runs on JDK 14, while the current snapshot runs on JDK 15.

Kind regards,

Arjan Tijms

Hi, is there any centralized information about compatibility of different Jakarta EE implementations/products with different OpenJDK versions?

Thanks
