public class JvmShutdownSafeguard extends Thread
When the JVM shuts down cleanly (SIGTERM or System.exit(int)
) it runs all
installed shutdown hooks. It is possible that any of the shutdown hooks blocks, which causes the
JVM to get stuck and not exit at all.
This utility installs a shutdown hook that forcibly terminates the JVM if it is still alive a certain time after clean shutdown was initiated. Even if some shutdown hooks block, the JVM will terminate within a certain time.
