           Summary: "name" and "message" enumerable on *Error.prototype
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Minor
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: erights at gmail.com

For all so-called NativeError.prototype objects, their "name" and "message"
properties are enumerable when they shouldn't be. Error itself has this problem for 'message' but not for 'name'.

The "message" property's value should be the empty string. But on all the NativeError.prototype objects its value is instead the same as "name" -- the name of the corresponding constructor.

I am classifying this as minor since an initialization script can easily repair
this using Object.defineProperty.
