I found a strange statement in the code [here](https://github.com/TransEmpiric/webFluxTemplate/blob/eac7eab14a08d9a4f911c9a3464b786c6b06c16a/src/main/java/com/transempiric/webfluxTemplate/config/security/JwtTokenUtil.java#L139) equals was called on itself. Was this intended as a placeholder, or an error?
