## What is the purpose of the change Backport of #27466 to release-2.2. ## Verifying this change - `./mvnw -pl flink-tests -am -Pskip-webui-build -Dtest='UnalignedCheckpointFailureHandlingITCase' -Dsurefire.failIfNoSpecifiedTests=false package` (JDK 17), run 5 times: `BUILD SUCCESS` every time, each with `Tests run: 1, Failures: 0, Errors: 0, Skipped: 0` - `./mvnw -q -pl flink-tests spotless:check checkstyle:check` (JDK 17): passed - The test method, `triggerFailingCheckpoint`, and the runtime code on the failure path (`ChannelStateCheckpointWriter`, `DefaultOperatorStateBackendSnapshotStrategy`) on release-2.2 were read and compared with the code the original fix was written against: the race is present here. ## Difference from the original | Original commit | Conflict | Byte-identical | Changes | | --- | --- | --- | --- | | fdf1a2e9dfc | No | Yes | None | ## Notes - This is a test-only flakiness fix, so there is no main-code change to revert. The flake was not reproduced on this branch before the change; the 5 runs show the test passes with the fix, not that the race was observed. cc @mateczagany @ferenc-csaky ##### Was generative AI tooling used to co-author this PR? - [X] Yes (please specify the tool below) Generated-by: Claude Code 2.1.316 (Claude Opus 5.5) -- This is an automated message from the Apache Git Service.
