Hello, I am running a suite of integration tests against Apache Cassandra v4. I may have discovered a possible regression that I thought to share/report.

Running Apache Cassandra as a Docker image using:
{code:java}
docker run --rm --name cassandra -d -p 9042:9042 cassandra:4.0{code}
produces the following error:
{code:java}

If the image tag is changed instead to be:
{code:java}
docker run --rm --name cassandra -d -p 9042:9042 cassandra:4.0-beta4{code}
Then all tests pass. I am not quite sure if this is a driver issue, or the server.

The test suite project is running OpenJDK 11.0.10.

Looks like Docker images pushed out to Docker hub for 4.0 and 4.0-rc1 (14 hours ago as of this writing) might have contributed to this.
