在head first java的第一个音乐播放器中出现了警告：
WARNING: 140: This application, or a library it uses, is using the deprecated Carbon Component Manager for hosting Audio Units. Support for this will be removed in a future release. Also, this makes the host incompatible with version 3 audio units. Please transition to the API's in AudioComponent.h.
出现警告提示的java版本是1.7，更新到1.8后解决。
