Hi @aparnajyothi-y, thanks for the PR. I work on the GraalVM at Oracle and contributed GraalVM support.

Instead of adding a note like this, we are using a different approach in setup-graalvm: we let java-version: '17' default to 17.0.12 and emit a job warning.

Do you think it would make sense to do the same in setup-java?

Hello @fniephaus, Thank you for the suggestion. Based on further investigation, it wouldn’t be feasible to adopt the same approach for Java 17 as in setup-graalvm at this time, because the end of GFTC support for version 17.0.12 has not yet been confirmed. As a result, we cannot be certain whether this will be the final update of Java 17 with GFTC license support, or if future versions will follow the same model.

Given this uncertainty, we’ve decided to update the documentation instead of implementing the same defaulting approach as in setup-graalvm.

We appreciate your understanding!

Hello @fniephaus, a gentle reminder to check if you have any further questions or need additional clarifications on the above.

Thanks for the ping, @aparnajyothi-y!

The blog post that introduced GFTC said the following about timelines:

"For designated Long Term Support releases (GraalVM for JDK 17), Oracle will provide these free GFTC releases until one full year after the subsequent LTS release".

According to the release calendar, Oracle GraalVM for JDK 17.0.12 is the last release under GFTC. The artifacts are still available and their license are not changed retroactively. In fact, the script-friendly URLs used by setup-java can only retrieve GFTC-licensed releases of Oracle GraalVM.

The end of permissive license was also announced here.

So, I'd still recommend to let 'java-version: 17' fall back to 17.0.12 while displaying a warning that notifies users of their options (upgrading to JDK 21 is recommended).

What do you think?
