----------------------------------------
Three more in the last week, again on master and release-2.3:
https://github.com/apache/flink/actions/runs/35299936102/job/105461658119
(master push, 2026-09-18)

(release-2.3 nightly, 2026-09-18)
https://github.com/apache/flink/actions/runs/35677983844 (release-2.3 nightly,
2026-09-22, in both the Hadoop 3.1.3 and the Java 21 core leg)
CachedShuffleDescriptorsTest hit the same message on release-2.2:
https://github.com/apache/flink/actions/runs/35767837856/job/106905457791
{code}
[ERROR]

It builds its scheduler with {{forMainThread()}} and
{{TestingUtils.defaultExecutorExtension()}}, the same combination your PR
replaces in ArchivedExecutionGraphTest, so it would make sense to cover it
there too.
