[lilliput-jdk17u:lilliput] RFR: 8312095: [Lilliput/JDK17] Reinstate use of BiasedLockingCounters

Fri Jul 14 12:16:56 UTC 2023

In x86_64.ad we accidentally dropped _counters to NULL in a fast_lock() call. This means we're not counting BiasedLocking calls correctly. Let's fix that. It is only relevant in 17 because biased locking has been removed in later release.

Testing:
 - [ ] tier1 +UseBiasedLocking
