以编程方式查找并加载jfxrt.jar启动一个坏主意？

Question

我有一个包含一些JavaFX代码的swing应用程序。我完全知道jfxrt.jar存在于lib而不是ext目录中的问题，默认情况下不可用。

给出：
 *我不想使用JavaFX Maven插件
 *我不想捆绑一个jre
 *我很高兴以编程方式解决没有Java Fx的系统（我只使用Java FX进行一些图表）

在我的应用程序启动时运行以下代码是否有任何问题？我已经在windows，mac和linux上使用各种jre测试了它，并且没有捆绑Java FX jar（OpenJDK / Oracle / Java7 / Java6组合等）。
