Covers three Java concurrency features: Phaser (Java 7) as a more flexible replacement for CountDownLatch/CyclicBarrier, StampedLock (Java 8) as a lightweight option for read/write locking in concurrent classes, and VarHandle (Java 9–11) as a safer alternative to sun.misc.Unsafe. Explains how each mechanism works and when to use each one.
