   • 2000, Douglas Lea, Concurrent Programming in Java, Addison-Wesley Professional, →ISBN, page 88:

     If synchronization is always performed in least-first order with respect to object tags, then situations can never arise in which one thread has the synchronization lock for x while waiting for y and another has the lock for y while waiting for x. Instead, they will both obtain the locks in the same order, thus avoiding this form of deadlock.
