Interestingly, the build does not fail in CI in mainline without this fix but it fails in jdk21u. I'm backporting [JDK-8313643](https://bugs.openjdk.org/browse/JDK-8313643), and the build fails in CI on Linux x64 with exactly the same error. The compilers used in 21u and mainline are the same. It's weird. ------------- PR Comment: https://git.openjdk.org/jdk/pull/16468#issuecomment-1799586417
