flex加载jwplayer的解决办法

(http://www.longtailvideo.com/players/jw-flv-player/), work within Adobe Flex.

This class is overlaps original class:

com.longtailvideo.jwplayer.utils.RootReference compiled in Player.

WARNING:

This class MUST be placed strictly in: com.longtailvideo.jwplayer.utils class path.
