Expected:

Object.keys([1,2,3])
["0","1","2"]
Object.getOwnPropertyNames([1,2,3])
["length","0","1","2"]

Result:

["0", "1", "2", "0", "1", "2"]
["0", "1", "2", "length", "0", "1", "2"]

and also with js_Iteratoror for (i in arr)

I cannot reproduce this behavior. Which version?

sorry for bothering you, finally found it...

I broke it myself (in jsR_setindex)
