This fix resolves an issue where the `Cipher.updateAAD(ByteBuffer)` method, when used on a ChaCha20-Poly1305 Cipher, may throw an exception due to an offset calculation error. This occurs when the ByteBuffer is array-backed, and when the buffer passed into the method is a slice of another array-backed buffer and that slice begins at a non-zero offset in the parent ByteBuffer.
Credit and thanks to @jaikiran for finding the issue and providing reproducer code. ------------- Commit messages: - Fix whitespace errors, add trailing newline - merge with main - 8366833: Poly1305 does not always correctly update position for array-backed ByteBuffers after processMultipleBlocks Changes: https://git.openjdk.org/jdk/pull/27081/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=27081&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8366833 Stats: 135 lines in 2 files changed: 133 ins; 0 del; 2 mod Patch: https://git.openjdk.org/jdk/pull/27081.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/27081/head:pull/27081 PR: https://git.openjdk.org/jdk/pull/27081
