> The benchmark test {{SerializationFrameworkMiniBenchmarks#serializerHeavyString}} became unstable mid of January 2022 which cannot be explained (see [graph|http://codespeed.dak8s.net:8000/timeline/#/?exe=1&ben=serializerHeavyString&extr=on&quarts=on&equid=off&env=2&revs=1000]). 
> There is some suspicion that it was caused by FLINK-25246 because Java 11 was added during that time.
