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!
