If a portlet .war does not contain WEB-INF/lib/log4j.jar then Liferay Portal 6.2 adds log4j as a dependency at deploy time. However, Liferay Portal 7.0 does not.

This task involves adding the log4j dependency to the pom.xml descriptor of each demo, so that it will be present at build time and so that logger messages can be seen when demo portlets are deployed to either Liferay Portal 6.2 or 7.0.
