>Description:
It is legal in Java for class to declare a method with the
same name as a default (package-private) method in a 
foreign-package superclass.

However, because it is invisible to the sub-class, the
method should NOT override the superclasses method 
declaration.

>How-To-Repeat:
Compile the following code:

// file: pkg1/A.java
package pkg1;
public class A 
{
  void foo () 
  {
    System.out.println ("A.foo()");
  }
  
  public static void main(String[] args) {
    A x = new pkg2.B();
    x.foo();
  }
}

// file: pkg2/B.java
package pkg2;
public class B extends pkg1.A 
{
  protected void foo ()
  {
    System.out.println("B.foo()"); 
  }
}

The correct output (as tested on IBM JDK 1.1.8 and Sun 1.2.2)
should read:

$ java pkg1.A
A.foo()

The gcj-compiled output is:

$ ./pkg
B.foo()
