Java 11 and Ubuntu Assistive technology not found AWTError   

While running a Java program on gnome - Ubuntu 18.04 and Linux Mint 19 (program working fine on Windows and Linux Mint 17) I faced the following error:

java.awt.AWTError: Assistive Technology not found: org.GNOME.Accessibility.AtkWrapper

The error was raised of this piece of code:

import java.awt.Robot
Robot r = new Robot();

The solution seems quite easy for Ubuntu/Linux Mint/gnome:

Java 11

• Edit file - /etc/java-11-openjdk/accessibility.properties
• Comment line - #assistive_technologies=org.GNOME.Accessibility.AtkWrapper

For Java 10:

/etc/java-10-openjdk/accessibility.properties

For Java 9:

/etc/java-9-openjdk/accessibility.properties

For Java 8:

/etc/java-8-openjdk/accessibility.properties

This can be done with script by:

sudo sed -i "s/^assistive_technologies=/#&/" \
/etc/java-11-openjdk/accessibility.properties
