Specifically, when one runs the test cases and looks at the logs of the
MiniKdc:
```java

```
This error is caused by the fact that sun.security module is no longer
supported in Java 16 and higher. Related to the [1].
There are two ways how to solve it, and I present one of them. The second
way is to export the ENV variable during the deployment of the containers using
Ducktape in [2].
