Render Embedded Fonts to a BitmapData in AS3 / Flex

Question

It seems that rendering fonts to a BitmapData in Flex is quite easy. You create a TextField, populate its properties, and the BitmapData's .draw() will accept it.

The problem comes in when you attempt to enable embedded fonts. Here is an example of what I'm trying to do:

ResourceManager.as:
public final class ResourceManager {
 /* .... */
 [Embed(source='assets/fonts/OratorStd.ttf', fontName="Orator Std", mimeType="application/x-font")]
 public static var OratorFontClass:Class; 
 public static function registerFonts():void{ 
  if(!fontsRegistered) {
   Font.registerFont(OratorFontClass);
   fontsRegistered = true;
  }
 }
 /* .... */
}



SomeOtherClass.as
public class SomeOtherClass {
 public function startup():void {
  ResourceManager.registerFonts();
 }

 public function render(output:BitmapData):void {
  var text:TextField = new TextField();
  var format:TextFormat = new TextFormat("Orator Std", 14, 0xFFFFFF,
   null, null, null, null, null, TextFormatAlign.CENTER);
  text.defaultTextFormat = format;
  text.embedFonts = true; /* <<---- When this is disabled, it works fine! */
  text.width = this.width;
  text.sharpness = 0; text.thickness = 0;
  text.antiAliasType = AntiAliasType.ADVANCED;
  text.gridFitType = GridFitType.SUBPIXEL;
  text.x = text.y = 0;

  /* ... */

  output.draw(text);

  /* ... */
 }
}

It seems that Flash refuses to render the embedded resource to the bitmap, and I have no idea why. I need to render the text to a bitmap as it's then applied to a backbuffer via applyFilter (to adjust transparency) - the end result is usage in a game that, obviously, is leveraging double buffering.
