If you compile the following two classes, class X will get a warning of the form:

x/X.java:6: Note: Method void foo() in class x.X does not override the corresponding method in class a.A, which is private to a different package.
    void foo() {
         ^
1 warning

This is bogus.  If A.foo() were private, no warning would be generated.
This is a situation where the compiler should be silent.  I should be
able to add a new package-accessible method to my classes without worrying
that I may generate warnings to every user about something that doesn't matter
to them (that I have an inaccessible member of the same name).

Here's the source

package a;

import x.X;

public class A {
    void foo() { }
    public static void main(String[] args) {
	X xref = new X();
	xref.foo();
    }
}

package x;

import a.*;

public class X extends A {
    void foo() {
	System.out.println("X's foo");
    }
}
