I meant that the implementation of `subSequence` *might or might not* perform copy (so we need to tell the javaDoc reader), while `getChar` *clearly* performs a copy as part of it design. So `subSequence` can be surprising as this discussion proofs, while `getChars` will not. That was Stuart's point with `read`, and that was your point with `CharSequence`. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/24728#discussion_r2089749078
