Right, it makes sense. A point to share is that we have all GWT modules with that property set to JDK 8, because I failed to compile our GWT sources with any JDK 8+, when I tried some months ago.

Tibor,
Thank you for your initiative, can you please clarify:
Phase 1:
- Setting the release property:
<maven.compiler.release>17</maven.compiler.release>.
That means that we currently have some modules with JDK version < 17,
right?
Phase 2:
- Update the KIE CI to use Java 21 by default. This means:
- Making sure PR checks run with Java 21.
- Making sure the release builds run with Java 21.
If I understood correctly, we have to support both JDK 17 and JDK 21 for a
while. Should we expect to have 2 subsets of PR Checks, one that runs
against JDK 17 and one that compiles against JDK 21 (optaplanner is
correctly doing that against JDK 17 and 20)?
Thanks
Yeser

Hi everyone,
as Java 21 is the latest Java LTS available, already for some time, I
would
like to propose that the code should be buildable and runnable with Java
21, while still retaining compatibility with Java 17.
The work should be split into two phases like this:
Phase 1:
- Setting the release property:
<maven.compiler.release>17</maven.compiler.release>.
- This should make sure the code works with Java 17.
- This should make sure that the existing CI still works the same way
and is able to build releases etc., because even if we have Java 17 as a
build environment, with the setting, it should work.
- Fixing the problems that occur while trying to build the repositories
with Java 21 and are caused by Java 21.
- Fixing the problems that occur while running tests with Java 21 and are
caused by Java 21.
- Updating the images we publish and need JDK to contain JDK 21 instead
of
17.
- Target of the work are all Apache KIE repositories, mainly:
incubator-kie-drools, incubator-kie-optaplanner,
incubator-kie-kogito-runtimes, incubator-kie-kogito-apps,
incubator-kie-kogito-examples, incubator-kie-tools.
Phase 2:
- Update the KIE CI to use Java 21 by default. This means:
- Making sure PR checks run with Java 21.
- Making sure the release builds run with Java 21.
What do you think, please? I plan to open a vote on Monday based on the
feedback of this discussion. Finding people to do this work is already
done, at least for Phase 1.
Best regards,
Tibor
