I updated all Jenkins agents to use Java 7 to build master branch and
moved all references from Java 6 to Java 7 in xwiki-commons root pom.
What it means in practice is that you might have issues building XWiki
with Java 6 from now on (and will probably be impossible in not long).
We don't yet used much Java 7 API but if you don't build everything on
your side you will probably have issues when building a project which
download on maven repository jars built with Java 7.
In short: update your Maven setup to use Java 7 when working with master branch.
Thanks,
