颠覆认知---java的构造函数一定会被执行吗？

import sun.misc.Unsafe;

import java.lang.reflect.Field;


public class Test {
    public Test(){
        System.out.println("exec");
    }
    public void s(){
        System.out.println("this s method");
    }
    public static void main(String[] args) throws InstantiationException {
         Unsafe unsafe = reflectGetUnsafe();

        Test test =  (Test)unsafe.allocateInstance(Test.class);
        test.s();
    }

    public static Unsafe reflectGetUnsafe() {
        try {
            Field field = Unsafe.class.getDeclaredField("theUnsafe");
            field.setAccessible(true);
            return (Unsafe) field.get(null);
        } catch (NoSuchFieldException | IllegalAccessException e) {
            e.printStackTrace();
        }
        return null;
    }
}

执行结果

结论：unsafe可以突破很多限制。。。。。。。构造函数不一定必须执行
