> Key: CASSANDRA-18113
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18113
> Project: Cassandra
> Issue Type: Bug
> Components: Tool/fql
> Reporter: n.v.harikrishna
> Assignee: n.v.harikrishna
> Priority: Normal

> Enable fullquerylog, prepare insert statement and bind it with a null value and execute it. Executing fqltool dump after insert will result into NullPointerException.
>
> Stept to reproduce:
> * Create cluster using ccm
> * Create a table something like:
> {code:java}
> CREATE TABLE ks1.t2 (
> id int PRIMARY KEY,
> value text
> ) ;
> {code}
> * Execute below code
> {code:java}
> try (CqlSession cqlSession = CqlSession.builder().build()) {
> PreparedStatement preparedStatement = cqlSession.prepare("INSERT INTO ks1.t2 (id, value) VALUES (?, ?)");
> cqlSession.execute(preparedStatement.bind(6, null));
> }
> {code}
> * Now running fqltool dump. It will run into NPE
>
>
> Stack trace:
> {code:java}
> error: null
> -- StackTrace --
