Please review a simple build change to re-enable the `-serialwarn` javadoc option for normal and reference API docs. The option was removed in [JDK-8252717](https://bugs.openjdk.org/browse/JDK-8252717) to avoid warnings for missing `@serial` tags which have since been added in [JDK-8286931](https://bugs.openjdk.org/browse/JDK-8286931).
I tested normal and reference docs builds, both run without warning and the generated documentation is unchanged. The `@serial` tag in the Exception template is required and also does not affect javadoc output. ------------- Commit messages: - 8287749: Re-enable javadoc -serialwarn option Changes: https://git.openjdk.org/jdk/pull/23802/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=23802&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8287749 Stats: 5 lines in 2 files changed: 2 ins; 0 del; 3 mod Patch: https://git.openjdk.org/jdk/pull/23802.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/23802/head:pull/23802 PR: https://git.openjdk.org/jdk/pull/23802
