Why no warnning as INVISIBLE in package and access control ?

Question

Hi all.
I have made sample source:
---------- Stock.java----------
package stock;
public class Stock {
private int x=1;
int y=2;
protected int z=3;
---------- PrintStock.java ----------
package printstock;
public class PrintStock extends stock.Stock{
public static void main(String[] args) {
PrintStock ps = new PrintStock();
ps.pl();
public void pl(){
// System.out.println(x);
// System.out.println(y);
System.out.println(z);
-----------------SampleC.java----------------------
package stock;
public class SampleC {
public static void main(String[] args) {
printstock.PrintStock ps = new printstock.PrintStock();
Stock s = (Stock) ps;
System.out.println(s.y); // *1
System.out.println(ps.y); // *2
When I use the eclips, *2 gets warning INVISIBLE.
But when I use the JDeveloper 11.1.2.1.0,
*2 gets no warning.
And when I run the sources on JDeveloer 11.1.2.1.0,
I get Error INVISIBLE.
This is a bug of JDeveloper 11.1.2.1.0 ???
Or is there an option parameter for warning INVISIBLE ?

Hi Frank!
Please check the behave on Eclips.
You might get the warning before run.
But you have no warning the behave on JDeveloper.
You might get the Error in running.
