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).
addshutdownHook is not invoked when sending a QUIT signal

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?

whats wrong with just kill? it shold send the default signal, SIGTERM
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.
