Fixed errors where Maven complains about the POM for uitest - "could not initialize class org.apache.maven.plugin.war.util.WebappStructureSerializer" and about the 'skip' option being incorrect for maven-javadoc-plugin (because it was missing a groupid declaration). Also silenced warning for explicitly set javax.servlet-api version.
