Calling to getter/setter method incorrectly

[NWU-NISL]

Description

As the following test case shown, when I get the attribute 2 of the object v0 in the tenth line, Rhino returns the setter method instead of calling the getter method. According to ECMA262, getter method should be called here, so v0[2] should return 1 instead of the setter method.

Version

1.7.13

Command

java -jar  rhino/rhino-1.7.13.jar -debug -version 200 testcase.js

testcase

function f() {
    var v0 = {
        get 2(){
            return 1;
        },
        set 2(value){
            throw new Error(2);
        }
    }
    var v1 = v0[2];
    print(v1);
}
f()

Output

function (value) {
    throw new Error(2);
}

Expected output

1
