摆动组件在javafx中显示为黑色

Question

我参加了一个团队项目，我们几乎完全是JavaFX，但是我们的日历是由一些JComponents（JTable）组成的，它按预期工作，除非我们运行代码它最初显示为黑盒子（图片＃1），直到调整阶段大小或执行其他操作。我在堆栈溢出（JavaFX and SwingNode - partial black Window）处查看了另一个问题，并且在那里声明它是更新31中的已知错误，并且已在更新40中修复。

我使用JDK 1.8u45运行代码，并且我或多或少地丢失了为什么会发生这种情况。这仍然是一个错误还是我的代码错了？

编辑：添加了我从测试应用程序中删除的代码
