Covers the full spectrum of Java concurrency from basic threads to Java 21's virtual threads, with solid coverage of executors, locks, and CompletableFuture patterns. The quick reference examples are practical, especially the virtual thread executor and CompletableFuture composition patterns you'll actually use in production. The thread pool sizing guidance is helpful, though real tuning always depends on your specific workload. Bonded to the advanced Java agent, so it can handle everything from debugging race conditions with jstack to configuring ThreadPoolExecutor rejection policies. If you're dealing with concurrent code beyond basic synchronized blocks, this will save you from the usual gotchas.
