Subject [jira] Updated: (HARMONY-403) HashMap hashcode ignores values in entries
Date Mon, 24 Apr 2006 12:52:07 GMT
     [ http://issues.apache.org/jira/browse/HARMONY-403?page=all ]

Mark Hindess updated HARMONY-403:
---------------------------------

    Attachment: hashmap.hashcodes.should.differ.diff

(Oops, attached these in the wrong order but JIRA wont really show this so I should have kept
quiet.)

The file "fix.hashmap.hashcode.diff" is a fix that I thought might fix the problem but actually
doesn't.  However, it still "smells" like a bug to me.

> While it is obviously trivial to create different HashMaps with identical hashCodes,
I'd still expect the following test code to pass:
>   HashMap map1 = new HashMap(10);
>   HashMap map2 = new HashMap(10);
>   map1.put("key", "1");
>   map2.put("key", "2");
>   assertFalse(map1.hashCode() == map2.hashCode());
> That is, I'd expect the 'value' associated with "key" to have some impact on the hashCode.
 It passes on the reference implementations I tested.
