Please review a set of updates to clean up use of `/**` comments in the vicinity of declarations.
There are various categories of update: * "Box comments" beginning with `/**` * Misplaced doc comments before package or import statements * Misplaced doc comments after the annotations for a declaration * Dangling `/**` comments relating to a group of declarations, separate from the doc comments for each of those declarations * Use of `/**` for the legal header at or near the top of the file In one case, two doc comments before a declaration were merged, which fixes a bug/omission in the documented serialized form. ------------- Commit messages: - JDK-8330178: Clean up non-standard use of /** comments in `java.base` Changes: https://git.openjdk.org/jdk/pull/18846/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=18846&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8330178 Stats: 134 lines in 23 files changed: 50 ins; 56 del; 28 mod Patch: https://git.openjdk.org/jdk/pull/18846.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/18846/head:pull/18846 PR: https://git.openjdk.org/jdk/pull/18846
