unclear diagnostic when anon class fails to override abstract pkg private method

FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)


FULL OPERATING SYSTEM VERSION :

A DESCRIPTION OF THE PROBLEM :
This is at least an inaccurate error message in the
compiler. It may also be a bug, preventing certain
things from compiling.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Just save the two files and compile.


ERROR MESSAGES THAT APPEAR :

The error message

> (926) javac -d dest *.java
> BBB.java:9: <anonymous buggy2.BBB$1> should be declared
> abstract; it does not define mm() in buggy1.AAA
> int mm() { return 3; }
> ^
> 1 error

is definitely not true. The fix is to change the method signature in AAA
to be
public abstract int mm();

The compiler should generate a more helpful or informative message.

This bug can be reproduced always.

------ BEGIN SOURCE -------
There are two files.


//// This is file AAA.java
package buggy1;
public abstract class AAA {
    abstract int mm();
}


//// This is file BBB.java
package buggy2;
import buggy1.AAA;

public class BBB {
    public void main() {
AAA aa = new AAA () {
int mm() { return 3; }
};
System.out.println("bbb");
    }
}
//// End of BBB.java
------- END SOURCE --------

CUSTOMER WORKAROUND :
Make the method public, or put the two classes in the same package.
