Comment 1 Olivier Thomann CLA 2005-04-09 11:28:45 EDT 
Would you have a test case to submit?
Comment 2 Tim Hanson CLA 2005-04-11 19:40:44 EDT 
The following simplified repro seems to do it:

import java.util.*;

class X {
        public static void main(String[] args) {
                Outer.Comparator<String> i = new Outer.Comparator<String>() {

                        public boolean equals(String a, String b) {
                                // TODO Auto-generated method stub
                                return false;
                        }

                        public int hashCode(String a) {
                                // TODO Auto-generated method stub
                                return 0;
                        }
                };

        }
}

class Outer {}
Comment 3 Philipe Mulet CLA 2005-04-12 04:29:34 EDT 
Thanks, reproduced in latest.

Added GenericTypeTest#test585.
Fixed will be integrated along with capture conversion changes (once clients
have converted).
