Overriding a method which is invoked from super-constructor issues a NPE

If two classes defined in script extend each other, and you overwrite a method 
which is called from the super constructor a NullPointerException is issued.

Example code:

{{{
public class A {
   int _id;
   public A (int id) {
      setId(id);
   }
   public void setId (int id) {
      _id = id;
   }
   public int getId() { return _id; }
}
public class B extends A {
   public B (int id) {
      super (id * 3);
   }
   public void setId (int id) {
      super.setId(id * 5);
   }
}
print(new B(1).getId());
}}}

Created a patch - seems a bit risky.
Need more test cases first.

Another test case, with an abstract class.
