Issues related to [JDK-8369335](https://bugs.openjdk.org/browse/JDK-8369335) (https://github.com/openjdk/jdk21u-dev/pull/2644) and [JDK-8378113](https://bugs.openjdk.org/browse/JDK-8378113) (https://github.com/openjdk/jdk21u-dev/pull/2645) will be addressed in separate dependent backport PRs.

Created [JDK-8378788](https://bugs.openjdk.org/browse/JDK-8378788) to report the issue and [JDK-8378789](https://bugs.openjdk.org/browse/JDK-8378789) (https://github.com/openjdk/jdk21u-dev/pull/2646) to add it to the problem list.
