Class ExecutorServiceShutdownHook

java.lang.Object

java.lang.Thread

com.aoapps.concurrent.ExecutorServiceShutdownHook

All Implemented Interfaces:

Runnable

public class ExecutorServiceShutdownHook
extends Thread

The threads of executor services can cause a JVM to keep running if they are not daemon threads. Additionally, daemon threads can be interrupted by an unclean shutdown if no shutdown hook is provided. By using this implementation of a shutdown hook you get the best of both - threads stop at the correct time, not too soon and not too late.
