What's the current consensus WRT Java 25 support in 3.4.3 ? Spark and other downstream projects want at least the SubjectInhertitingThread changes in 3.4.3 so that they can run their Hadoop dependent tests (and production) with Java 25 ASAP.
Ideally, we'd have CI tests for Java 25 for trunk, and then backport everything required for Java 25 support to branch-3.4 and add Java 25 tests there as well, but that would take quite a lot of time, as we don't even have Java 25 CI set up for trunk yet, and more than a dozen changes would need to be backported to branch-3.4 to fix all tests and corner cases with Java 25. I can probably make the time to backport the SubjectInhertitingThread changes next week to branch-3.4 if there is consensus on merging them there.
