Matthias commented on FLINK-24331:
----------------------------------
We're experiencing this issue also on the VVP Flink 1.14 fork:
https://dev.azure.com/ververica-dev/daplatform-flink/_build/results?buildId=1566&view=logs&j=cc649950-03e9-5fae-8326-2f1ad744b536&t=a9a20597-291c-5240-9913-a731d46d6dd1&l=11085
I'm going to add the affected version accordingly and add the build's artifact
for investigation.
