Please review this PR that aims to add all the remaining needed `@since` tags in `java.base`, and group them into a single fix. This is related to #18934 and my work around the `@since` checker feature. Explicit `@since` tags are needed for some overriding methods for the purpose of the checker.
I will only give the example with the `CompletableFuture` class but here is the before where the methods only appeared in "Methods declared in interface N" <img width="1510" alt="Screenshot 2024-05-06 at 00 06 57" src="https://github.com/openjdk/jdk/assets/96922791/1749a355-133b-4a38-bffe-51ac415b2aac";> and after where the method has it's own javadoc, the main description is added and the `@since` tags are added as intended. I don't have an account on `https://cr.openjdk.org/` but I could host the generated docs somewhere if that is needed. <img width="1511" alt="Screenshot 2024-05-06 at 00 07 16" src="https://github.com/openjdk/jdk/assets/96922791/89b92288-9b5e-48ed-8fa1-9342ea43e043";> <img width="1505" alt="Screenshot 2024-05-06 at 00 08 06" src="https://github.com/openjdk/jdk/assets/96922791/9aef08ff-5030-4189-a996-582a7eef849b";> <img width="1050" alt="Screenshot 2024-05-06 at 00 09 03" src="https://github.com/openjdk/jdk/assets/96922791/fdd75a26-0396-4c5e-8f59-a3717b7d7ec8";> TIA ------------- Commit messages: - remove couple extra lines - Pull request is now only about `@since` tags, might add an other commit - add one more `{inheritDoc}` to `CompletableFuture.state` - add `@throws` declarations to javadoc - add ``{@inheritDoc}`` to new javadoc comments - remove two extra spaces - add tags to elements from `java.base` Changes: https://git.openjdk.org/jdk/pull/18954/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=18954&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8330954 Stats: 71 lines in 14 files changed: 66 ins; 2 del; 3 mod Patch: https://git.openjdk.org/jdk/pull/18954.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/18954/head:pull/18954 PR: https://git.openjdk.org/jdk/pull/18954
