686799 - Object.freeze() on String-Object throws java.lang.IllegalStateException

Status: RESOLVED WORKSFORME

(Rhino Graveyard :: Core, defect)

Description

[André Bargull [:anba]]

Attachment: Chapter15_Object_freeze.java

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0.2) Gecko/20100101 Firefox/6.0.2
Build ID: 20110902133214

Steps to reproduce:

Called Object.freeze() on a String-Object.

See test262 for the original test case:
test/suite/ietestcenter/chapter15/15.2/15.2.3/15.2.3.9/15.2.3.9-2-a-12.js


Actual results:

IdScriptableObject.setInstanceIdValue() throws a "java.lang.IllegalStateException: 1" exception.


Expected results:

Object.freeze() should not throw any exceptions per ES5 spec.

The IllegalStateException is no longer reproducible in rhino_1_8 (haven't tested master yet), so this bug report can be closed. 

The original test262 test case ("15.2.3.9-2-a-12.js") will still fail, but that's another issue:
`Object.getOwnPropertyDescriptor(new String('a'), '1')` currently returns `undefined` instead of `{configurable: false, enumerable: true, writable: false, value: 'a'}`. 

=> Should I create a new bug report for that issue?

IllegalStateException is no longer reproducible (see above), therefore resolving as WFM.
Created bug 726297 to track the [[DefineOwnProperty]] changes required for NativeString.
