Martijn Visser commented on FLINK-38534:
----------------------------------------
Three more, one of them the first on release-2.2:
https://github.com/apache/flink/actions/runs/36084551382/job/107923102308
(release-2.3, nightly 2026-09-25, AdaptiveScheduler, JDK 17)

(release-2.3, nightly 2026-09-28, test_cron_azure, JDK 17)

(release-2.2, nightly 2026-09-27, test_cron_hadoop313, JDK 17)
On release-2.3 these are the "Exhausted retry attempts" and "Job ... is not a
streaming job." variants. release-2.2 fails with an NPE while the acknowledged
checkpoint is finalized, and its fork log has no "Cannot deploy" line:
{code}
[ERROR]

That is six of 27 runs on release-2.3 and one of 16 on release-2.2 in the last
seven days, none on master.
