| Re: [gef-dev] Java 21 for GEF-Classic |
I personally prefer that we also consider the consumers who are generally best served with the least restrictive requirements.
As I understand it, Tycho will run tests using the configured
Java 17 in the tool chain if the project says its test runs on
Java 17.
Of course at some point some plugin dependency on which a GEF
bundle depends will change its bound to 21 and then only building
against an older target platform would allow for actual testing of
Java 17 via actual tests. If that happens during the current
2025-03 release cycle, that might require to revisit the
decision. And of course another important consideration is what
is easiest and the least work for the developers. It's definitely
nice to be able to use the latest language features!
As always I prefer moving to the latest Java if possible. So +1 for moving GEF to Java 21 (for the 2025-03 release).

_______________________________________________Hello everyone,
The Eclipse Platform SDK now requires Java 21 due to the dependency to Lucene 10.x which has already led to build problems that could be seen here [1]. The latest GEF-Classic build uses a workaround, to get both the Java 17 and Java 21 builds happy, but even that is no longer possible with recent SimRel changes. In short: We are no longer able to build and test GEF-Classic against Java 17, using the 2025-03 staging repository.
This now also raises the question when we should officially drop support for Java 17. As part of the Simultaneous Release, we are allowed to move to Java 21 since 2024-06, so all formal requirements have already been satisfied. Personally, I would either target the next release (as part of 2025-03) or the release after that (2025-06). Given that we're very early in the release cycle, both options seem valid.
What are your thoughts on this?
Many regards,
Patrick

The latest Orbit summary table includes details about the required Java version of each library prompted by Lucene 10's requirement for Java 21 which is first library in Orbit to require Java 21:
