The previous code did not verify lack of bci overlap AFAICT, it just picked one; do I need to update the bug description or open a new one to add that? That said, if we guarantee there's no overlap (fail fast) then we only have to loop over the array once, which is better still. ------------- PR Comment: https://git.openjdk.org/jdk/pull/20841#issuecomment-2327017308
