addshutdownHook is not invoked when sending a QUIT signal

Question

I would like to terminate the Java application when 'kill -s 3 ' is executed. But Java dumps the thread information instead. Do I need to use different kill signal?

what **resource** you want to clean up using shutdownhook? – PankajSays Nov 12 '13 at 18:13 — PankajSays, Nov 12 '13 at 18:13

take a look at this: How to stop java process gracefully?

kill -3 or kill -s 3 will always generate the thread dump.

In general programming, finalizer and shutdownhooks should not be used.

According to JVMs and kill signals, the ShutdownHook is not run and the jvm is not shutdown when using signal SIGQUIT (3). Just use the default signal SIGTERM (15).
