java - Ubuntu、JavaFX、Java 运行时环境检测到 fatal error

Question

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(但不是每次都这样):

#

它不会每次都发生，但大部分都会发生。通常在我第一次启动eclipse并运行我的程序后就没有问题。

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.

但没有任何帮助....我不知道该怎么办。

编辑:当我在 Windows 上运行相同的代码时没有问题。

编辑2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。

首先，当您寻找 JavaFX 问题时，为 SWT 设置选项对您没有帮助。 SWT 仅在 Eclipse 内部使用。 JavaFX 应用程序作为新进程启动，不会注意到同一台计算机上的另一个 Java 应用程序正在使用 SWT。

从堆栈跟踪来看，本地事件循环 (GtkApplication.enterNestedEventLoopImpl) 检测到“按键”事件 (process_events -> WindowContextBase::process_key).在 JavaFX 方面似乎有一个事件处理程序，因为代码接下来会尝试调用 void 方法 (JNIEnv_::CallVoidMethod) 然后崩溃。

我不确定 static 字段在这里有什么影响；按键操作也很常见，因此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 中引起了无穷无尽的问题，已经过时了图片。但是，也许您或其他人为桌面选择了一个比 Gtk 2 使用的默认主题“更好”的主题。我建议:

1. 尝试将主题重置为默认主题
2. 为您的 Linux 安装最新的补丁
3. 创建一个只包含问题的精简版代码。
4. 尝试为 JavaFX 和一些演示运行“Hello World”应用。
5. 如果失败，尝试打开一个针对 OpenJDK 的错误:https://bugs.openjdk.java.net/secure/Dashboard.jspa
