Description

[RJ Budzynski]

User-Agent:       Mozilla/5.0 (compatible; Konqueror/3.5; Linux) KHTML/3.5.6 (like Gecko) (Kubuntu)
Build Identifier: Rhino 1.6 release 7 2007 08 30

The behavior differs from that specified in http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Reference:Global_Objects:Array:forEach#Description
as well as from what spidermonkey does, in the case when the array contains undefined elements.

Reproducible: Always

Steps to Reproduce:
js> var a = (new Array(2)); a.forEach( function (e, i, a) { a[i] = i; } ); a.toSource();


Actual Results:  
prints [0, 1]

Expected Results:  
the array should consist of two undefined elements, as per the documentation and consistently with spidermonkey.
