----------------------------------------
Another one on release-2.3, Azure nightly 2026-10-22 (test_cron_azure core, JDK
17):
https://dev.azure.com/apache-flink/98463496-1af2-4620-8eab-a2ecc1a2e6fe/_build/results?buildId=80390&view=logs&j=77a9d8e1-d610-59b3-fc2a-4766541e0e33
The fork log has the reason for the exit code 239. A Netty event loop thread
hit an IllegalAccessError while freeing its buffer cache, while
testCloseAsyncShouldNotCleanUpHAData was starting its actor system:
