Java 9 banDuplicateClasses incorrectly sees module-info.class as duplicate

When running the enforcer plugin with banDuplicateClasses rule against a project with dependencies on java-9 compatible libraries which include a module-info.class file, the plugin sees the multiple module-info files as duplicate classes.

It should simply ignore these similar to package-info.

In our projects, it is the dependencies on multiple libs from org.ow2.asm which provides the module-info class, rendering the following output:

[WARNING] Rule 2: org.apache.maven.plugins.enforcer.BanDuplicateClasses failed with message:
Duplicate classes found:

  Found in:
    org.ow2.asm:asm-tree:jar:6.0:compile
    org.ow2.asm:asm:jar:6.0:compile
    org.ow2.asm:asm-util:jar:6.0:compile
  Duplicate classes:
    module-info.class

We can easily work around this problem for now by adding a global rule to ignore module-info such as the following but it would be nice if the enforces plugin ignored this file by default.

<banDuplicateClasses>
	<ignoreClasses>
		<ignoreClass>module-info</ignoreClass>
	</ignoreClasses>
</banDuplicateClasses>
