Functions inside with statements dont get correct scope

from Andreas Rieber <rieberandreas@gmail.com>:

The next one is about scopes in file: jdk8/jdk/src/share/sample/scripting/scriptpad/src/resources/scriptpad.js. I removed everything unimportant and the following code snippet show the problem:

------
var guiPkgs = { JFrame: function() { print("created"); } };

with (guiPkgs) {
   function main() {
       function createFrame() {
           var frame = new JFrame();
       }

       createFrame();
   }
}

main();

------

'created' should come out but JFrame is unknown. I tested this with some browsers (Firefox, Safari, Chrome) but only Rhino and Firefox can handle that construct.
