Java Edition:Invalid Name Johnny Vindicator

By updating Johnny vindicators through the same versions to get a long name mob, you can get a vindicator that is not named Johnny but still has the same behavior as a Johnny vindicator.

Obtaining

Firstly, you would have to name a vindicator Johnny. The recommended version is 16w39a, as updating the vindicator will create an axeless vindicator. Then, update to 18w21b - 18w22a. This will change the vindicator's name to {"text":"Johnny"}. Even though this vindicator's name is not Johnny, it still has its Johnny tag set to true.
