Description

This happening regular on the python driver CI and it's reasonable to assume that C* is under heavy load when it happens. The CQL command sent is

CREATE KEYSPACE keyspace WITH replication " = {'class': 'SimpleStrategy', 'replication_factor': 1}

or

CREATE TABLE table_name (k INT, i INT, PRIMARY KEY(k, i))

The error the driver gets is

<Error from server: code=0000 [Server error] message="java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.NullPointerException">
