This issue tracks all the issues and pull requests related to improving the JDK infrastucture on nixpkgs (See https://discourse.nixos.org/t/improve-the-jdk-infrastructure-on-nixpkgs/)

I will continue to update this issue as new pull requests or issues are created. While discussions should primarily take place on the corresponding issues themselves, feel free to leave a comment here if you believe something relevant has been missed.

Does #301653 count as a JDK version update automation? Even though JBR is pretty specifically for JetBrains IDEs…

[Infinidoge]

It does. Whether we like it or not, it's a JDK.

286267 has been split into a number of smaller PRs:

• 313920 (merged)

• 313923 (merged)

• 313925 (draft)

• 313927 (open)

• 313928 (draft)

• 313929 (merged)

• 314377 (open)

• 314378 (open)

• 314380 (open)

• 314381 (open)

I expect several of these to need to be switched over to staging, but I'm waiting until OfBorg evals them and until I have enough spoons to actually do that. I've already accidentally failed one cross-branch rebase today, I'm not going it again.

Lesson learned, break up PRs as much as possible.

Cross-compilation of openjdk is also wildly broken, as the entire dependencies within javaPackages do not get spliced properly, and several dependencies are added as buildInputs instead of nativeBuildInputs
