I believe https://issues.apache.org/jira/browse/MJAVADOC-387 introduced a regression as it overrides any value set in {{additionalparam}} which only manifests when using the maven release plugin 

My open source project ([AssertJ|http://joel-costigliola.github.io/assertj/index.html]) adds javascript to the javadoc footer I thus need to add this parameter to be able to generate the javadoc:
{{<additionalparam>--allow-script-in-comments</additionalparam>}}

The {{mvn release:perform}} command failed with this error:
{noformat}
[INFO] Exit code: 1 - javadoc: error - Argument for -footer contains JavaScript.
[INFO] Use --allow-script-in-comments to allow use of JavaScript.
{noformat}

the debug log shows that the {{--allow-script-in-comments}} parameter I set was not honored:
{noformat}
[INFO] [DEBUG] Configuring mojo 'org.apache.maven.plugins:maven-javadoc-plugin:3.0.0-M1:jar' with basic configurator -->
[INFO] [DEBUG]   (f) additionalparam = -Xdoclint:none
{noformat}
