This PR could use the feature it introduces. It would test drive the feature and ensure that the feature works. A brief search showed these potential candidates in test/langtools/jdk/javadoc/:

  1. doclet/InheritDocForUserTags/DocTest.java:57
  2. tool/BadOptionsTest.java:83,96,108,120,132
  3. doclet/testCustomTagletRegistration/TestRegistrationErrors.java:76
  4. doclet/testSnippetTag/SnippetTester.java:55
