Chirstian! you should read Vincent's email with title "Coding Convention".

Thanks

It would be cool if all committers used the coding conventions have
defined and agreed upon. There are Eclipse and IDEA configuration
files for them here: http://www.xwiki.org/xwiki/bin/view/Community/CodeStyle

Generally speaking all committers should read everything that's on
http://www.xwiki.org/xwiki/bin/view/Community/

Feedback is welcome BTW but unless someone says something this is
what we've agreed on previously and what should be used.

Thanks
-Vincent
