Our automatic post-integration audits found that [JDK-8391651](https://bugs.openjdk.org/browse/JDK-8391651) missed the spot. It fixed the compareAndSetFlatValueAsBytes (CAS) case, but missed compareAndExchangeFlatValue (CAE) case.
A symmetric test case readily fails without the fix. I just copied the CAS test and replaced call with CAE. Additional testing: - [x] New regression test fails without the fix, passes with it --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - Fix Changes: https://git.openjdk.org/jdk/pull/33150/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=33150&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8393318 Stats: 54 lines in 2 files changed: 53 ins; 0 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/33150.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/33150/head:pull/33150 PR: https://git.openjdk.org/jdk/pull/33150
