NetBeans 6.0 RC2:

Try "Encapsulate field" for "h" in the following codes and
uncheck "Use Accessors Even When Field Is Accessible" option
It works in NB5.5.1.

--
public class Main{
    class A{
        int h;
    }

    class B extends A{
        void m(){
            System.out.println(h);
        }
    }
}
--

Result NB6.0:
h should be getH() in method m.
--
public class Main{
    class A{
        private int h;

        public int getH() {
            return h;
        }

        public void setH(int h) {
            this.h = h;
        }
    }

    class B extends A{
        void m(){
            System.out.println(h);
        }
    }
}
--

Result NB5.5.1: it's correct.
--
public class Main {
    class A{
        private int h;

        public int getH() {
            return h;
        }

        public void setH(int h) {
            this.h = h;
        }
    }

    class B extends A{
        void m(){
            System.out.println(getH());
        }
    }
}
