When a safepoint is reached during execution of the JIT compiled code, one or more locks eligible for conversion to a biased lock are identified .based on the recorded access information for each of the identified locks, one or more locks eligible for conversion to a biased lock. Each respective lock of the one or more eligible locks is converted to a biased lock based on a current lock status of the respective lock.
