12-Nov-2018 12:31:09.743 WARNING [localhost-startStop-1] se.jiderhamn.classloader.leak.prevention.JULLogger.warn Consider adding -Djava.awt.headless=true to your JVM parameters

the setting that is mentioned in the last line is set with JAVA_OPTS and CATALINA_OPTS. i don't know whether this error has any effects.

Kathrin-Huber commented 5 years ago

I can not reproduce this error, is it still a problem?

matthias-ronge commented 4 years ago

As I see it, it's because the Tomcat's JVM is not running in headless mode. Please adjust your Tomcat start settings and add -Djava.awt.headless=true to the JVM arguments. (I read that, alternatively, you can install the package libfontconfig1 using apt-get, which can also fix this.)

i stopped evaluation kitodo a while ago. and i don't remember how i deployed it and how the docs could be improved in this regard.
