I belive there is a bug in `AbstractMemorySegmentImpl#mismatch` method. It returns `-1` (meaning that regions are equal) when passing the same instance of MemorySegment as both `srcSegment` and `dstSegment` parameters regardless of whether `srcFromOffset` and `dstFromOffset` as well as `srcToOffset` and `dstToOffset` are also equal.
Am I right? ------------- Commit messages: - fix mismatch avoidance of memory comparison Changes: https://git.openjdk.org/jdk/pull/17354/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=17354&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8323552 Stats: 1 line in 1 file changed: 0 ins; 0 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/17354.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/17354/head:pull/17354 PR: https://git.openjdk.org/jdk/pull/17354
