[SOLVED] Jenkins fails to start due to NullPointerException

schard · 2021-01-07 12:56:02

I am trying to setup Jenkins as per the wiki.
When I access the web-frontend, I get presented with the following error message:

AWT ist auf diesem Server nicht vollständig konfiguriert. Eventuell sollten Sie Ihren Servlet-Container mit der Option -Djava.awt.headless=true starten.

java.lang.NullPointerException

I also tried to inject the suggested parameter into Jenkin's config file:

$ cat /etc/conf.d/jenkins 
JAVA=/usr/lib/jvm/java-8-openjdk/jre/bin/java
JAVA_ARGS=-Xmx512m
JAVA_OPTS=-Djava.awt.headless=true
JENKINS_USER=jenkins
JENKINS_HOME=/var/lib/jenkins
JENKINS_WAR=/usr/share/java/jenkins/jenkins.war
JENKINS_WEBROOT=--webroot=/var/cache/jenkins
JENKINS_PORT=--httpPort=8090
JENKINS_AJPPORT=--ajp13Port=-1
JENKINS_OPTS=-Djava.awt.headless=true
JENKINS_COMMAND_LINE="$JAVA $JAVA_ARGS $JAVA_OPTS -jar $JENKINS_WAR $JENKINS_WEBROOT $JENKINS_PORT $JENKINS_AJPPORT $JENKINS_OPTS"

# vim:set ts=2 sw=2 et:

I tried it with both, as JAVA_ARGS and JENKINS_OPTS as well as with only one of those set.
However, after a restart, these params don't seem to have an effect on the error message.
Did anybody else encounter this and has found a solution?

Solution
Yet again, I was too impatient.
Installing fontconfig fixed the issue.
