As per JEP 374 (see ~~JDK-8231264~~) biased-locking was marked for obsoletion in JDK 16, but it was decided (~~JDK-8256253~~) to defer that to JDK 18.
Code associated with VM options UseBiasedLocking, BiasedLockingStartupDelay, BiasedLockingBulkRebiasThreshold, BiasedLockingBulkRevokeThreshold, BiasedLockingDecayTime, UseOptoBiasInlining, PrintBiasedLockingStatistics and PrintPreciseBiasedLockingStatistics can be removed.
