> During Kerberos re-login, we log out and login again. There is a timing issue
> where the principal in the Subject has been cleared, but a new one hasn't
> been populated yet. We need to ensure that we don't throw
> AuthenticationException in this case to avoid Kafka clients
> (consumer/producer etc.) failing instead of retrying.
