After fixing the bug

• Github Action and
• Travis matrix builds should be changed to at least contain 8, 11, 17, and maybe 18-ea/19-ea (as of 2022-02-10) - https://www.oracle.com/java/technologies/java-se-support-roadmap.html
• Fix errors resulting from running with more modern builds:
  • Javadoc error on JDK17 and JDK18 relates to https://bugs.openjdk.java.net/browse/JDK-8270866
  • RatCheckMojo complaining about module error
