Comment 1 Frederic Fusier CLA 2005-04-10 07:00:34 EDT 
Can you provide a more detailed test case to helpme to reproduce (what kind of
refs were you searching, using search dialog or direclty from popup-menus, etc...)?
Thanks
Comment 2 Adam Kiezun CLA 2005-04-10 10:33:13 EDT 
don't remember exactly but i think i selected a declaration of a method in an
anonymous class and (i'm sure of that one) did : search for references in
project (from menu)
Comment 3 Frederic Fusier CLA 2005-04-10 10:49:05 EDT 
I guess you were editing 1.5 code, right?
Would be possible that you put it in this bug?
Comment 4 Frederic Fusier CLA 2005-04-10 10:57:45 EDT 
I got it with following simple test case:
import java.util.*;
public class X<T> {
	void foo() {
		List<String> list = new ArrayList<String>() {
			public boolean add ( String o) {
				return false;
			}
		};
		list.add("");
	}
}
Select add method declaration and search for reference in project...
Thanks for the info
Comment 5 Adam Kiezun CLA 2005-04-10 11:00:40 EDT 
yup, i just got a 'mid-air collision' when i about to submit a test case
virtually identical to yours.
Comment 6 Frederic Fusier CLA 2005-04-10 17:20:22 EDT 
Fixed and release in HEAD.

[jdt-core-internal]
Test case added in JavaSearchBugsTests.
Comment 7 Maxime Daniel CLA 2005-05-12 09:18:33 EDT 
Verified for 3.1 M7 using build I20050509-2010 + jdt.core HEAD.
