With Cassandra 2.2.11, I get this error instead:

> Key: CASSANDRA-13991
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13991
> Project: Cassandra
> Issue Type: Bug
> Components: CQL
> Reporter: Chris mildebrandt
> Priority: Major
> Attachments: CASSANDRA-13991.log
>
>
> Performing the following steps (using the gocql library) results in an NPE:
> * With a table of 12 entries, read all rows.
> * Set the page size to 1 and read the first row. Save the query state.
> * Read all the row again.
> * Set the page size to 5 and the page state to the previous state. (This is where the NPE occurs).
> This can be reproduced with the following project:
