As identified in #11214 (comment) Javadoc checks have javadoc comments having // violation in them. We used to have this before we added support of // violation X lines below.

Now we should refactor such tests to remove // violation comment from javadoc comments.

Example of a check having this issue - JavaDocStyleCheckTest

All cases to fix:

$ grep -rl "// violation" | grep -E "*Test\.java"
