As noted in https://bugs.openjdk.org/browse/JDK-8387996, the `jinfo` and `jstack` man pages still recommend using the `-J-d64` option when attaching to a 64-bit JVM.
The `-d64` option has not been available since JDK 10. This patch removes the obsolete guidance from both man pages. --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - 8387996: Remove reference to -d64 from serviceability tool manpages Changes: https://git.openjdk.org/jdk/pull/31872/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=31872&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8387996 Stats: 8 lines in 2 files changed: 0 ins; 4 del; 4 mod Patch: https://git.openjdk.org/jdk/pull/31872.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/31872/head:pull/31872 PR: https://git.openjdk.org/jdk/pull/31872
