Please review a doc-only change to mostly add missing `@serial` javadoc tags. This is a sub-task of [JDK-8286931] to allow us to re-enable the javadoc `-serialwarn` option in the JDK doc build, which has been disabled since JDK 19.
[JDK-8286931]: https://bugs.openjdk.org/browse/JDK-8286931 For private and package-private serialized fields that already have a doc comment, the main description is converted to a block tag by prepending `@serial` since these fields do not require a main description. For protected and public serialized fields that require a main description, an empty `@serial` block tag is appended to the doc comment instead. The effect is the same, as the main description is used in `serial-form.html` if the `@serial` tag is missing or empty. For those fields that do not have a doc comment, a doc comment with an empty `@serial` tag is added. Apart from missing `@serial` tags, this PR also adds a `@serialData` tag to `java.awt.datatransfer.DataFlavor.writeExternal(ObjectOutput)` that the javadoc `-serialwarn` option complains about. This is the only change in this PR that adds documentation text and causes a change in the generated documentation. ------------- Commit messages: - 8347123: Add missing @serial tags to other modules Changes: https://git.openjdk.org/jdk/pull/22980/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=22980&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8347123 Stats: 107 lines in 39 files changed: 45 ins; 0 del; 62 mod Patch: https://git.openjdk.org/jdk/pull/22980.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/22980/head:pull/22980 PR: https://git.openjdk.org/jdk/pull/22980
