---------------------------------------------
hey folks, is anyone actively working on this one?
> Verify the snapshot migration on Java21
> ---------------------------------------
>
> Key: FLINK-33699
> URL: https://issues.apache.org/jira/browse/FLINK-33699
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Checkpointing
> Reporter: Yun Tang
> Priority: Major
>
> In Java 21 builds, Scala is being bumped to 2.12.18, which causes
> incompatibilities within Flink.
> This could affect loading savepoints from a Java 8/11/17 build. We already
> have tests extending {{SnapshotMigrationTestBase}} to verify the logic of
> migrating snapshots generated by the older Flink version. I think we can also
> introduce similar tests to verify the logic across different Java versions.
