This seems to be a known issue on Ubuntu 24.04 + Java.
This error occurs from
[20251017.1|[https://dev.azure.com/apache-flink/apache-flink/_build/results?buildId=70314&view=results].]
But the same commit is passed in
[20251016.9|[https://dev.azure.com/apache-flink/apache-flink/_build/results?buildId=70304&view=results].]
I am not sure whether the update to ubuntu 24.04 is the root cause.
