Timeline for support of JDK 25?

[magnus-larsson]

Do you have a timeline for when this build pack will support JDK 25?

Thanks

[dmikusa]

Largely dependent on the vendor, but see this thread for more info:

[magnus-larsson]

Java 25 support is now in place, see https://github.com/paketo-buildpacks/bellsoft-liberica/releases/tag/v11.3.0.

Thanks!

Awesome to hear! Do I need to specify the JDK version explicitly? I'm on 11.3.0 but still getting

no valid dependencies for native-image-svm, 25

From what I saw in the release https://github.com/paketo-buildpacks/bellsoft-liberica/releases/tag/v11.3.0, the NIK that is the one responsible of native image building is not yet on java 25. For now only JDK and JRE images are on that buildpack. I think we will need to wait until next release to include the native image kit.

I see, thanks! I opened a new issue for that, see #883
