 <!-- The following checklist is mainly intended for yourself to verify that you did not miss anything -->
 
-- [ ] New code follows the [Google Java Style Guide](https://google.github.io/styleguide/javaguide.html)
+- [ ] New code follows the [Google Java Style Guide](https://google.github.io/styleguide/javaguide.html)\
+  This is automatically checked by `mvn verify`, but can also be checked on its own using `mvn spotless:check`.\
+  Style violations can be fixed using `mvn spotless:apply`; this can be done in a separate commit to verify that it did not cause undesired changes.
 - [ ] If necessary, new public API validates arguments, for example rejects `null`
 - [ ] New public API has Javadoc

The JSONPath `$.languages[2]` in the exception message also points there: `$.` refers to the root object, `languages` refers to its member of that name and `[2]` refers to the (missing) third value in the JSON array value of that member (numbering starts at 0, so it is `[2]` instead of `[3]`).

 To spot syntax errors in the JSON data easily you can open it in an editor with support for JSON, for example Visual Studio Code. It will highlight within the JSON data the error location and show why the JSON data is considered invalid.
