 Hello,
 
 this PR was filed against (then current) gcc 3.0 snapshot. Would it be  
 possible to determine if this problem is still present in current 3.3  
 or mainline, and update the report accordingly? Thanks,
 
 Dara

gcc version 2.96 20000525 (experimental)
>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()
