MartijnVisser opened a new pull request, #29401: URL: https://github.com/apache/flink/pull/29401
Unchanged backport of #29386, which is approved but not merged on master yet. `getRunningFetcher()` has the same `isEmpty()`-then-`next()` race on release-2.3, so `addSplits()` can fail with `NoSuchElementException` when a fetcher removes itself in between. `testGetRunningFetcherSurvivesFetcherRemovalInToctouWindow` fails without the fix, with the ticket's `NoSuchElementException`, and passes with it on JDK 17. `SplitFetcherManagerTest`, `spotless:check` and `checkstyle:check` pass. ##### Was generative AI tooling used to co-author this PR? - [X] Yes (please specify the tool below) Generated-by: Claude Code (Claude Opus 5.5) -- This is an automated message from the Apache Git Service.
