> 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.
