A DESCRIPTION OF THE PROBLEM :
AFAIU https://bugs.openjdk.org/browse/JDK-8347811 affects JDK21, JDK17 and older as well. Since they are in wide use would it be possible to backport the fix for 25 to the older JDKs?

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
```
# docker run -it --rm eclipse-temurin:21.0.7_6-jdk-alpine-3.20 /bin/sh
