hotspot:::vm-shutdown is not always fired.
It is fired only when System.exit method is invoked.

To observe different behavior of vm-shutdown probe run:
   
a)
   1. java -XX:+UnlockDiagnosticVMOptions -XX:+PauseAtPauseAtStartup HelloWord &

   2. ./vm_lifecycle_pid.d <java_pid>
 
   3. no vm-shutdown probe is fired

b)
   1. java -XX:+UnlockDiagnosticVMOptions -XX:+PauseAtPauseAtStartup HelloWordExit &

   2. ./vm_lifecycle_pid.d <java_pid>
 
   3. vm-shutdown probe is fired
