Hi Slide, 

I'm still unable to start Jenkins via Systemd service although I'm using Java 8 but I'm able to start Jenkins manually. See below output for your information. 

Java 8

======

# java -version

openjdk version "1.8.0_151"

OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.16.04.2-b12)

OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

Start Jenkins using systemd 

======================

# systemctl start jenkins

Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details.

Check Jenkins status

=================

# systemctl status jenkins.service

Start Jenkins manually

=================

# su - jenkins -c '/usr/bin/daemon --name=jenkins --inherit --env=JENKINS_HOME=/var/lib/jenkins --output=/var/log/jenkins/jenkins.log --pidfile=/var/run/jenkins/jenkins.pid -- /usr/bin/java -Djava.awt.headless=true -jar /usr/share/jenkins/jenkins.war --webroot=/var/cache/jenkins/war --httpPort=8080'

Check Jenkins status

================

# ps -ef | grep -i [j]enkins

jenkins   2674     1  0 15:17 ?        00:00:00 /usr/bin/daemon --name=jenkins --inherit --env=JENKINS_HOME=/var/lib/jenkins --output=/var/log/jenkins/jenkins.log --pidfile=/var/run/jenkins/jenkins.pid -- /usr/bin/java -Djava.awt.headless=true -jar /usr/share/jenkins/jenkins.war --webroot=/var/cache/jenkins/war --httpPort=8080
