Tuesday, February 19, 2013 JVMs and kill signals Ever wondered how a JVM reacts to various kill signals? The (intended) behaviour might be documented somewhere already, but I found having a table of > the actual behaviour available quite useful. In particular I wanted to know which kill signals trigger the JVM to run registered shutdown hooks, and > > which kill signals don't actually terminate the JVM. So I decided to compile a table of that information.

I wrote up a small Java application that just registers a shutdown hook that I can detect whether it has executed or not, and then sleeps until I get a chance to kill it:
