Frank,

We've found a few more bugs we'd like to report -- if we were still
at Sun we would simply file them with bugtool :-(

We'd appreciate it if you could tell us whether (1) you know about
this bug, (2) it's fixed already in some version we'll get eventually,
or (3) it's scheduled for FCS. I guess if it's decided that it won't
be fixed, we'd like to know that, too.

Thanks a bunch,

-Rafael


Compile the following test. It will give a strange error message:

Main.java:25: Reference to clone is ambiguous. It is defined in
java.lang.Object clone() and java.lang.Object clone().
    r.clone();
    ^
1 error

If the "i2" interface is used instead of the "i3" interface in "o2"
and "Main", then the error is not generated.


interface i1 extends java.lang.Cloneable {
  public Object clone();
}
interface i2 extends i1 {
}
interface i3 extends i2 {
}

class o1 {
  public Object clone()
    throws java.lang.CloneNotSupportedException
  {
    return super.clone();
  }
}

class o2
    extends o1
    implements i3
{ }

public class Main {
  public static void main(String argv[]) {
    i3 r = (i3)new o2();
    r.clone();
  }
}
