Information about a lock. A lock can be a built-in object monitor, an ownable synchronizer, or the Condition object associated with synchronizers.
An ownable synchronizer is a synchronizer that may be exclusively owned by a thread and usesAbstractOwnableSynchronizer (or its subclass) to implement its synchronization property. ReentrantLock andReentrantReadWriteLock are two examples of ownable synchronizers provided by the platform.
