Package ditaa seems to contain versioned jar files in %{_javadir}
(/usr/share/java). Such versioned files cause problems for automatic
requires generation and violate packaging guidelines[1].

List of subpackages and contained versioned jars
ditaa:
/usr/share/java/ditaa-0.9.jar


There are cases where this can be a false positive. Most likely if:
   * your package is compatibility version and contains only versioned
     jars
   * your package has version in the name of jars that are part of
     package name

Thank you,
