Bug#898821: maven-plugin-tools: FTBFS with Java 10 due to com.sun.tools.doclets removal

[Emmanuel Bourg]

Control: tags -1 + fixed-upstream

This issue has been "solved" upstream in the version 3.6 by dropping
support for javadoc annotations. This means we have to convert the
plugins still using these javadoc annotations to use the Java
annotations instead [2].
