      Description

        Every Error object gets a new PropertyMap after a recent change to capture stack trace @ constructor call.

            var e1 = new Error()
            var e2 = new Error()

            print(Debug.map(e1) == Debug.map(e2))

        prints false. Previously, the above evaluated to true. "nashornException" property is added to the instances at constructor. Note that previously error objects got exception property only when thrown -- at which these objects still got different PropertyMaps.

        try {
           throw e1
        } catch (e) {
            print(Debug.toIdentString(Debug.map(e)));
        }

        try {
           throw e2
        } catch (e) {
            print(Debug.toIdentString(Debug.map(e)));
        }

        I think it is better to add nashornException as a @Property to NativeXYZError classes.
