I don't really see why:

  public class TestJIT {
    public static void main(String[] args) {
        for (int i = 0; i < 20_000; i++) {
            payload();
        }
    }

    public static int payload(int a, int b) {
        return a + b;
    }
  }

shouldn't be optimized into a 'no-op'. The end-effect is the same.
