Rui Fan commented on FLINK-35040:
---------------------------------
Thanks [~slfan1989] and [~rmetzger] for the comment!
I didn't find any related issue from commons-io JIRA[1]. Also, I ran benchmark
on my Mac with jdk11, and try to analyze why code path causes this regression.
I use async-profiler wall mode to analyze the benchmark, and didn't find any
code from commons.io package.
Do you have any idea to troubleshooting?

> yet recovered on April 8th.
> It seems Java 11 regresses, and Java 8 and Java 17 are fine.
