Aside from moving up the copyright section, what should be the name of the copyright owner?

For example:

• Mockito has chosen Mockito contributors as the copyright owner.
• MapStruct has chosen MapStruct Authors as the copyright owner.

On the other side, projects like JUnit, Spring Framework and Spring Boot use the generic copyright definition:

Copyright ... the original author or authors.

@scordio I'm ok with the generic copyright as it is used by major open source projects.

Then I guess it's just a matter of moving the copyright at the beginning (although I don't see why it would make a legal difference)

Indeed, it's mostly a cosmetic issue.

In addition, our config can be simplified now that mathieucarbou/license-maven-plugin#532 ~is~ will be fixed but in the next release only 😅.

So, on hold until license-maven-plugin 4.6 is released.
