Here you're writing `cookie.length()` but early you write calculate with
`secureCookie.getBytes().length`. I think this causes issues with non ASCII
chars.

> design doc._
> Service-level authorization is the initial authorization mechanism to ensure
> clients (or servers) connecting to the Flink cluster are authorized to do so.
> The purpose is to prevent a cluster from being used by an unauthorized
> user, whether to execute jobs, disrupt cluster functionality, or gain access
> to secrets stored within the cluster.
> Implement service-level authorization as described in the design doc.
> - Introduce a shared secret cookie
> - Enable Akka security cookie
> - Implement data transfer authentication
> - Secure the web dashboard
