This is what I was afraid of @mstormi although at the time of the original PR it was installing fine, I worried that installing openjdk 21 from unstable would lead to dependency issues. This is why I advocated for Temurin because it was not dependent on unstable packages.

I can try and see if there is any easy fix for this but I'm not sure that there will be.

Let me know your thoughts.

I think we must not make openJDK21 the default before it's transitioned to stable repo by Debian maintainers.
By then however I think it's going to become and remain the recommendation simply because it's what most people will use in the long run.
So we should not be actively promoting (recommending) anything else like Temurin as that would mean we have to change our recommendation and communicate it broadly, with a remaining risk that we need to change recommendation forth and back a few times before things settle. Which always leaves a feeling that we don't know well enough what we're up to.

Hi! I also ran into the issue that there is no openjdk21 package in the Debian 12 Docker container. So I added a fallback to install Temurin whenever the required JDK package is missing.

[ecdye]

As much as I agree with your reasoning, I don't know if we can wait until it's in stable.

We are planning OH 5 for this summer but I'm not sure that there is a Debian release scheduled before that time, meaning our only choice is openJDK from unstable or another option like Temurin

[mstormi]

Tried testing repo instead of unstable, same problem.

[ecdye]

Maybe we should just make our official policy openJDK where possible through release channels with an appropriate and acceptable alternative of Temurin where openJDK is unavailable or unsuitable.

[mstormi]

okay, would you write something for NEWS.md? That we can refer to from OH release notes, forum etc

[mstormi]

wrong button :)

[ecdye]

Yeah, I'll try to add that this weekend.

@BClark09 wrote something about he added a Java17/21 check to the linux-distro package, maybe check that first
