IIRC those Java5 annotations are only used by the maven-plugin-plugin to
generate META-INF/maven/plugin.xml and are not used by the core Maven runtime,
in which case a retention policy of CLASS is ok:
http://svn.apache.org/viewvc?view=revision&revision=1338003
The main benefit of using them is that if you extend a Maven plugin then the
maven-plugin-plugin can see the Java5 annotations retained in the class file,
whereas javadoc annotations are only in the source.
See http://jira.codehaus.org/browse/MPLUGIN-56 for the original use-case.
