Getting Atk/Swing errors running a report

[johnmanko]

I created a Docker Image using CE 6.4.0 (which you can find at jmankoago/jasperserver:6.4.0).

Everything spins up in Docker just fine, and I'm able to add Reports. When running a Report, however, I get an error: java.awt.AWTError: Assistive Technology not found: org.GNOME.Accessibility.AtkWrapper:
docker_service_logs_jasperserver_jasperserver.txt

2017-08-10 17:59:44,693 ERROR JRFillSubreport,pool-4-thread-1:866 - Fill 1: exception
java.awt.AWTError: Assistive Technology not found: org.GNOME.Accessibility.AtkWrapper

Subsequent attempts to run that same report give a different error: java.lang.NoClassDefFoundError: Could not initialize class javax.swing.RepaintManager:

Could not initialize class javax.swing.RepaintManager.txt

2017-08-10 18:08:05,997 ERROR JRFillSubreport,pool-4-thread-2:866 - Fill 1: exception

The (modified) Dockerfile used to build the image:

FROM tomcat:8-jre8

The (modified) scripts/entrypoint.sh script:

tomcat-users.xml (which didn't seem to work, but this is unrelated - just here for completeness):

<tomcat-users>
	<role rolename="manager-gui"/>
	<user username="admin" password="admin" roles="manager-gui"/>
</tomcat-users>

@johnmanko the error doesn't seem to have anything to do with docker setup. Have you tried building locally and running report?
Also, pls try setting JAVA_OPTS - java -Djava.awt.headless=true
and restart server.
The server requires to have graphical environment for fonts and other graphic related routines that are part of the Java AWT. Lets see if starting JVM with an option for headless support helps.
