The root of the problem is the automatic module name generation of the jool-java-8 jar file. By default it becomes jool.java.8 and a number by itself is an illegal portion of a module name.
Without using "Automatic-Module-Name" your project builds on the classpath as always. When including that, it attempts to build on the module path and the Javadoc plugin apparently does not handle that well. I fought similar issues for a while and eventually got rid of the problematic dependency. You might try moditect to insert a module name of your choice. You might try approaching the authors of jool-java-8 and requesting they provide a valid automatic module name.
