How to determine when an attribute is changed by calling reflection methods

Question

I have the following class

public class MyClass {
   private int myAttr;

   public void setAttr(int a) { 
      myAttr = a; 
      Thread.dumpStack();
   }
}

Thus, I can detect any attempt to change myAttr. Well, almost anyone. It does not work when someone cheats myAttrusing a method Field.set(). How can I catch the use of Java reflections?

Answer 1

You can not. You are in power SecurityManagerif someone is nearby so that someone else does not make trouble against you.
