Question

I have the following class

public class MyClass {
   private int myAttr;

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

That way I can detect any attempt to modify myAttr. Well, almost any. It does not work when someone modifies myAttr using Field.set() method. How can I trap Java reflection usage?

Answer 1

You can’t. You’re at the mercy of the SecurityManager, if one is around, to prevent anyone else from doing nasty things to you.
