> CertificateRenewerService is submitted with scheduleAtFixedRate. If the task
> throws an unchecked exception, the executor cancels every further execution,
> and the exception is only stored in a Future that nobody inspects, so nothing
> is logged. The component then never renews its certificate again.
> The failure is silent when it happens and only becomes visible days later,
> when the certificate reaches its expiry, and the service can no longer
> authenticate to the cluster. Recovery needs a restart, and by then there is
> no evidence of what stopped the renewal.
