issue with Cassandra in pekko-sample-distributed-workers-scala

On a stable Debian (OpenJDK 17), the example pekko-sample-distributed-workers-scala will fail on a exception while using `sbt run` or `sbt "runMain worker.Main cassandra"`.

```

Start with worker.Main.startCassandraDatabase at Main.scala:101 and reproduce the failure using sbt run or sbt "runMain worker.Main cassandra" on Debian with OpenJDK 17. Check how the bundled Cassandra process starts and identify the cause of the InaccessibleObjectException; done means the sample starts Cassandra successfully without this startup exception.
