    Description

      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.
