How can I reproduce EXCEPTION_STACK_OVERFLOW error in Java

Question

How can I reproduce EXCEPTION_STACK_OVERFLOW error in Java.

PS: I am not talking of StackOverflowError Error in Java which gracefully shuts the JVM. I am talking of EXCEPTION_STACK_OVERFLOW in error.log which cause JVM to crash.

please double check your PS, I guess there's a tiny not missing in between "am" and "talking" ... – Benzidine

Most EXCEPTION_STACK_OVERFLOW errors I found so far happen in native code outside the JVM... If there was one inside, it would be a bug and to be fixed. – Benzidine

Not exact answer, but somehwat is there at https://mcmap.net/q/40894/-how-do-you-crash-a-jvm – Hafiz

Answer 1

Most EXCEPTION_STACK_OVERFLOW errors I found so far happen in native code outside the JVM. A crash inside the JVM is worth a bug report and will be fixed. Or are you in need of an (unknown) exploit?

So the easist and most reliable way would be to write a native library with some code that causes the JVM to crash and call that with JNI.

(general answer, I actually don't know how to do it exactly. Can't be done with java code only ;) )

+1. I can do +1 only but wanted to do +100 for confirming my understanding. Most of the others has mentioned about StackOverFlowError! – Hafiz

Answer 2

Blow stack:

public static void main(String[] args) {
    main(null);
}

Blow heap:

public static void main(String[] args) {
    List<String> list = new ArrayList<String>();
    while(true) list.add(new String("boom"));
}

None of the above would cause JVM crash. First one will cause StackOverflowError and second would cause OutOfMemoryError. – Hafiz

Answer 3

public static void stackoverflow()
{
     stackoverflow();
}

Call it, and enjoy :D

This would cause StackOverflowError and not JVM crash! – Hafiz
