Hi, Thanks to Marko Bekhta we have an updated JavaDoc stylesheet.css now which works when building with Java 9. Currently that file is stored locally within Hibernate Validator [1], but what do you all think about moving the stylesheet into a separate resource project under the "org.hibernate.infra" group id? That way all the Hibernate projects can pull it in during their build and benefit from maintaining the file in a single place. --Gunnar [1] https://github.com/hibernate/hibernate-validator/blob/master/src/main/jav...
