JavaFx-线程中无休止的异常；JavaFX应用程序线程；java.lang.NullPointerException

我得到以下异常，甚至无法理解它出现在什么地方。这意味着什么

这也发生在我身上，我只想写下我是如何解决它的。答案是：我是从非JavaFX线程编辑GUI的。我完全相信我不是，但我是。如果存在此问题，请检查您的代码，并使用

Platform.runLater（）

在正确的JavaFX线程中运行GUI更改。

@Jens您完全错了。我知道什么是nullpointerexception。问题是关于javafx的，因为问题出现在标准java库的某个地方，而不是我的代码中，正如您从日志中看到的那样。所以，请删除您的“副本”有任何代码发布sir@Elltz我有大约30个与javafx链接的类。哪一个？我真的说-我甚至不明白你在看什么。看起来你在布局过程中遇到了一个异常，所以每一个脉冲都会发生一个异常。请创建一个链接并发布它。否则很难找到问题……第一个异常与其他异常不同，看起来它发生在某个

Text

节点上。如果显式地有

Text

节点，我将从那里开始。正如@fabian所指出的，在布局过程中会出现异常。即使您有大量的类，您也可以独立地显示由这些类的小子集表示的布局子集，以便缩小异常的原因。
