我已经安装了ubuntu 14.04.02 x64，oracle jdk 1.8.4，我尝试运行JavaFX8项目，但我在eclipse中收到此消息（但不是每次都收到）：

这不是每次都发生，但大多数情况下，通常没有问题后，我启动eclipse和运行我的程序第一次。
我在互联网上寻找答案，并尝试了这个：

sudo unlink /usr/lib/x86_64-linux-gnu/libsoup-2.4.so.1

还有这个：

I've tried adding the the below line to the end of eclipse.ini, but Eclipse can't start at all:

org.eclipse.swt.browser.DefaultType=mozilla
I think there is some typo error, the line should be:

-Dorg.eclipse.swt.browser.DefaultType=mozilla
and this worked for me.

但是什么都帮不上忙...我不知道该怎么办。

**EDIT：**在Windows上运行相同的代码时没有问题。
EDIT2我发现，当我像这样使用静态变量时：

Stage primaryStage = Main.primaryStage;
primaryStage.setMaximized(true);

这会导致错误。

我已经把bug报告填到javafx jira中了。链接是这个(link to the bug)。
我试着在我的笔记本电脑上重现我的错误（mac和oracle jdk 1.8.0_45），也试着在虚拟机中使用ubuntu（ubuntu 14.04和相同版本的jdk），但错误没有发生。
上一次在聊天室，你说你在eclipse中使用open jdk时遇到了问题。那么，你能试着使用open jdk但从命令提示符运行应用程序吗？你可以试着使用这个命令运行它（假设你已经正确配置了jdk）。

java -cp .:controlsfx-8.20.8.jar:mysql-connector-java-5.1.35-bin.jar model.Main

看起来像是javafx link to duplicate bug的一个bug。尽管它被标记为这个问题link to original bug的副本。
基于问题的状态，bug已经被解决，所以也许你可以尝试更新你的jdk到最新版本，看看问题是否仍然发生。

当我展示的TextInputDialog（在展示主阶段之前）有一个CSS样式表，它使用@font-face声明了一个我已经删除的字体文件时，这个问题就出现了。通过删除这些过时的声明，这个问题就不再出现了。
有趣的是，这个问题只发生在我用键盘按回车键的时候。用鼠标接受对话框并没有导致这个问题。
（JavaFX 18）
另外，我以前也遇到过这个bug，但次数很少。我修复的这个问题导致了100%的错误。还有一个“javafx.css.cssParser reportException警告：请报告java.lang.NullPointerException at：“错误，这使我能够通过逐个删除每个样式表来跟踪它。

首先，当您查找JavaFX问题时，设置SWT选项并没有帮助。SWT仅在Eclipse内部使用。JavaFX应用程序作为一个新进程启动，不会注意到SWT被同一台计算机上的另一个Java应用程序使用。
从堆栈跟踪来看，本地事件循环（GtkApplication.enterNestedEventLoopImpl）似乎检测到了一个“按键”事件（process_events-〉WindowContextBase::process_key）。JavaFX端似乎有一个事件处理程序，因为代码接下来尝试调用void方法（JNIEnv_::CallVoidMethod），然后崩溃。
我不确定static字段在这里会有什么影响;按键也不罕见，所以这应该是经过良好测试的代码。
此外，JavaFX似乎使用了Gtk 2（libgdk-x11-2.0.so.0），这意味着Gtk 3的主题在SWT和Eclipse中会导致无休止的问题。但是，也许您或其他人为桌面选择了一个比Gtk 2默认使用的主题“更好”的主题。我建议：
1.尝试将主题重置为默认主题
1.为您的Linux安装最新补丁程序
1.创建一个只包含问题的精简版代码。
1.尝试运行JavaFX的“Hello World”应用程序和一些演示。
1.如果失败，请尝试打开OpenJDK的错误：https://bugs.openjdk.java.net/secure/Dashboard.jspa
