[jdk21u] RFR: 8318895: Deoptimization results in incorrect lightweight locking stack

Fri Nov 24 11:56:17 UTC 2023

Hi all,

This pull request contains a backport of commit [ea1ffa34](https://github.com/openjdk/jdk/commit/ea1ffa34192448317ce9a61a3588b0dee3a2ef44) from the [openjdk/jdk](https://git.openjdk.org/jdk) repository.

The commit being backported was authored by Roman Kennke on 10 Nov 2023 and was reviewed by Dean Long and Richard Reingruber.

The fix affects only lightweight locking paths and has not accrued bug-tail in mainline during the last 2 weeks.

Thanks!
