Assistive Technology not found: org.GNOME.Accessibility.AtkWrapper 的问题解决

前言

今天在学习Antlr4的时候遇到了这个问题,如下：

Exception in thread "main" java.awt.AWTError: Assistive Technology not found: org.GNOME.Accessibility.AtkWrapperat java.awt.Toolkit.loadAssistiveTechnologies(Toolkit.java:807)at java.awt.Toolkit.getDefaultToolkit(Toolkit.java:886)at javax.swing.RepaintManager.<clinit>(RepaintManager.java:238)at javax.swing.JComponent.repaint(JComponent.java:4792)at java.awt.Component.repaint(Component.java:3311)at org.antlr.v4.gui.TreeViewer.updatePreferredSize(TreeViewer.java:129)at org.antlr.v4.gui.TreeViewer.setTree(TreeViewer.java:800)at org.antlr.v4.gui.TreeViewer.<init>(TreeViewer.java:118)at org.antlr.v4.gui.Trees.inspect(Trees.java:25)at org.antlr.v4.gui.Trees.inspect(Trees.java:32)at org.antlr.v4.gui.TestRig.process(TestRig.java:213)at org.antlr.v4.gui.TestRig.process(TestRig.java:166)at org.antlr.v4.gui.TestRig.main(TestRig.java:119)

在github上看到了回答，大概是
它似乎是由 openjdk 软件包的无人注意的安全升级引起的。

解决方法

通过编辑OpenJDK的accessibility.properties文件
sudo vim /etc/java-8-openjdk/accessibility.properties
注释掉下面一行
assistive_technologies=org.GNOME.Accessibility.AtkWrapper
