--------------------------------------
Hi all, I reproduced the bug locally and raised a bugfix for it in
[26241|https://github.com/apache/flink/pull/26241].
As described in the PR, this bug is only a missing code in test case. It does
not affect production code so is not a blocker issue for release-2.0.
Besides, this test failure is not related to the OOM in the log, as it can be
found that successful CIs also have this OOM in the log ([example
CI|https://dev.azure.com/apache-flink/apache-flink/_build/results?buildId=66387&view=logs&j=77a9d8e1-d610-59b3-fc2a-4766541e0e33&t=125e07e7-8de0-5c6c-a541-a567415af3ef]).
The OOM has existed in release 1.20 ([example
CI|https://dev.azure.com/apache-flink/apache-flink/_build/results?buildId=66388&view=logs&j=77a9d8e1-d610-59b3-fc2a-4766541e0e33&t=125e07e7-8de0-5c6c-a541-a567415af3ef&l=1043])
so should also not be a blocker for 2.0.
