FontFamily in spark Flex 4

Question

Hi.
For my current project I am using spark components from the Flex 4.
I have some embedded fonts which I include with a css-file.
When I try to set the fontFamily, for example for the spark.component.textarea, the textarea displays System Arial font.
When I change the compiler to Flex 4.1 the spark component displays the embedded font.
Is it a bug in the version 4.0 or do I make something wrong?
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:ns="library://ns.adobe.com/flex/spark">
  <mx:Style source="fonts.css"/>
  <ns:TextArea fontLookup="embeddedCFF" fontFamily="TimesItalic" heightInLines="NaN" widthInChars="NaN" x="300" y="50" text="Embedded Font"/>
</mx:Application>
CSS:
@font-face {
        src: url("Families/TIMES_IT.TTF");
        fontFamily: TimesItalic;
        embedAsCFF: true;

Answer 1

Possibly.
There were a number of bug fixes between the Flex 4.0 and 4.1 releases (as well as an upgrade TLF).
This seems to work as expected in Flex Hero:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark"
               xmlns:mx="library://ns.adobe.com/flex/mx">
    <s:controlBarContent>
        <s:Button id="sdkVer" initialize="sdkVer.label = mx_internal::VERSION;" click="System.setClipboard(sdkVer.label);" />
    </s:controlBarContent>
    <fx:Style source="fonts.css"/>
    <s:TextArea text="Embedded Font"
                fontFamily="TimesItalic"
                fontStyle="italic"
                x="300" y="50" />
</s:Application>
And my fonts.css is as follows:
/* CSS file */
@namespace s "library://ns.adobe.com/flex/spark";
@namespace mx "library://ns.adobe.com/flex/mx";
@font-face {
    src: url("C:/Windows/Fonts/times.ttf");
    fontFamily: TimesItalic;
@font-face {
    src: url("C:/Windows/Fonts/timesi.ttf");
    fontFamily: TimesItalic;
    fontStyle: italic;
