With 3 little changes I have gained about 500 MB, but I still have to make sure everything still works. - 200 of those MB where gained by a commonly used trick : adding "--no-install-recommends" option to apt-get. Some packages that are commonly installed with libreoffice might have been skipped and I still have to determine if it's OK or not. - The other 300 MB are safe. Most of it comes from "RUN chown -R tomcat8:tomcat8 /var/lib/tomcat8" being moved inside the same layer as the curl xwiki.war && unzip.
