Archlinux package depends on Java8, I switch it to Java11
As I am wrtiting teses lines, https://archlinux.org/packages/community/any/jenkins/ depends on Java8.
But Jenkins recommends to use Java11: https://www.jenkins.io/doc/upgrade-guide/2.303/#upgrading-to-jenkins-lts-2-303-1
Well, I like dangerous life, so I decided to manually switch it to Java11.
This is done in one file: /etc/conf.d/jenkins
#JAVA=/usr/lib/jvm/java-8-openjdk/jre/bin/java JAVA=/usr/lib/jvm/java-11-openjdk/bin/java
