Description

After upgrading to Cassandra 3.11.8, Cassandra no longer starts. An exception is thrown:

 java.lang.RuntimeException: Client SSL is not supported for non-blocking sockets (hsha). Please remove client ssl from the configuration.

No configuration changed between 3.11.7 and 3.11.8. rpc_enabled is false in both versions.

I created this Jira issue because clearly something changed between 3.11.7 and 3.11.8. Maybe intentional, maybe not. Changing `rpc_server_type` (which is not clearly documented to be about Thrift only) from `hsha` to `sync` does resolve the issue, as expected, but this does seem like a regression, hence the Jira issue.
