How do you crash a JVM?

Question

I was reading a book on programming skills wherein the author asks the interviewee, \"How do you crash a JVM?\" I thought that you could do so by writing an infinite for-loo

Answer 1

Does this count ?

long pid = ProcessHandle.current().pid();
try { Runtime.getRuntime().exec("kill -9 "+pid); } catch (Exception e) {}

It only works for Linux and from Java 9.

For some reason I don't get, ProcessHandle.current().destroyForcibly(); doesn't kill the JVM and throws java.lang.IllegalStateException with the message destroy of current process not allowed.
