javafx - 调用 showSaveDialog() 和 showOpenMultipleDialog() 时出现 fatal error

Question

当我运行这两行时，JVM 崩溃了:

javafx.stage.FileChooser fileChooser = new FileChooser();
File targetFile = fileChooser.showSaveDialog( mainStage );

我在 Ubuntu 16.10、OpenJDK 8 64 位上:

openjdk version "1.8.0_131"
OpenJDK Runtime Environment (build 1.8.0_131-8u131-b11-0ubuntu1.16.10.2-b11)
OpenJDK 64-Bit Server VM (build 25.131-b11, mixed mode)

内核版本:

Linux Joshua-PC 4.8.0-59-generic #64-Ubuntu SMP Thu Jun 29 19:38:34 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

我尝试了此处概述的解决方案但没有成功:https://stackoverflow.com/a/34612376/61248

Answer 1

这是由使用外部库引起的 JNativeHook对于全局热键，尤其是这一行:

GlobalScreen.registerNativeHook();

还有这一行:

GlobalScreen.addNativeKeyListener( globalHotkeyListener );

我不明白为什么这会导致问题，但是删除这两个调用可以解决问题。 我想我必须寻找一个不同的全局热键库。

我与库开发人员进行了交谈。他检查了崩溃并说它不会直接发生在库中，他表示问题可能出在“xcb”和 linux 上。他建议使用较早版本的库(v2.0.2 而不是 v2.1.0)并解决了这个问题。
