> Steps to reproduce:
> 1. Start cassandra
> 2. Start cqlsh and paste the following in quick succession:
> {code:java}
> USE system;
> DROP KEYSPACE IF EXISTS my_keyspace;
> CREATE KEYSPACE my_keyspace WITH replication = { 'class': 'SimpleStrategy', 
> 'replication_factor': 1};
> USE my_keyspace;
> CREATE TABLE schema_version (id int primary key, version int, migration_lock 
> text);
> INSERT INTO schema_version (id, version) values (1, 0);{code}
> 3. Once fourth time or so , we'll see:
> {code:java}
> cqlsh:system> CREATE KEYSPACE my_keyspace WITH replication = { 'class': 
> 'SimpleStrategy', 'replication_factor': 1};
> ServerError: java.lang.RuntimeException: 
> java.util.concurrent.ExecutionException: java.lang.NullPointerException{code}
> or
> {code:java}
> cqlsh:my_keyspace> CREATE TABLE schema_version (id int primary key, version 
> int, migration_lock text);
> ServerError: java.lang.RuntimeException: 
> java.util.concurrent.ExecutionException: java.lang.NullPointerException{code}
