I've changed the HashMap into a LinkedHashMap in

For the additionalDependencies I need to investigate it a bit more. If you
think that is still required, please create a new issue with a minimal project
to demonstrate why you need it.

> The order of the classpath entries being generated in
> {{AbstractJavadocMojo.getPathElements()}}
> (https://github.com/apache/maven-javadoc-plugin/blob/12dbbde29cf6277ca311cb8afffdf02dbfe0c9b4/src/main/java/org/apache/maven/plugins/javadoc/AbstractJavadocMojo.java#L2601)
> is internally relying on a {{HashMap}} for the compile time artifacts. That
> is an issue if the classpath is not 100% clean (i.e. the same package is
> exported by multiple artifacts) because then the success depends on the order
> which is not predicable for regular {{HashMaps}}. Unclean classpaths are
> unfortunately pretty common in reality.
> To make builds more reliable please use a {{LinkedHashMap}} instead as that
> will keep the insertion order.
> Also since elements being returned first have a higher precedence the ones
> being maintained via {{additionalDependencies}} should be added first (after
> the module's target directory but before the compileArtifacts) to allow to
> enforce usage of a certain module for dedicated classes.
