$ java -jar aprof-plot.jar
Exception in thread "main" java.awt.AWTError: Assistive Technology not found: org.GNOME.Accessibility.AtkWrapper

Possible explanations I saw here was to install Java-access-bridge. But I am unable to install libaccess-java-bridge.

I ran into this same error on my Ubuntu 15.10 server but did not want to install the non-headless version of OpenJDK due to the number of additional dependencies. A simpler solution was to simply disable assistive technologies.

This can be done by editing the file for OpenJDK 8 (change the version to whichever is actually in use on your system):

sudo vim /etc/java-8-openjdk/

Comment out the following line:


Also you can edit this line programmatically:

sudo sed -i -e '/^assistive_technologies=/s/^/#/' /etc/java-*-openjdk/
