vmassol has changed the sample/pom.xml because the maven-surefire-plugin has a bug:
<!-- TODO: Version 2.2 of the surefire plugin is broken.
See http://jira.codehaus.org/browse/MSUREFIRE-145. Once it's fixed we'll be able
to remove this version element -->
It still doesn't built because the main pom.xml pulls the maven-surefire-plugin 2.2.
the patch change the main pom.xml the same way vmassol has changed sample/pom.xml
