Description

The following snippet fails on the current 2.0 branch and succeeds on the 2.1 branch.

create KEYSPACE test WITH replication = {'class': 'SimpleStrategy', 'replication_factor': 1};

USE test ;

CREATE TABLE lock (
	partition text,
	key text,
	owner text,
	PRIMARY KEY ((partition), key)
) WITH COMPACT STORAGE;

INSERT INTO lock(partition,key,owner) VALUES ('a','b',null) ;

UPDATE lock SET owner='z' WHERE partition='a' AND key='b' IF owner=null;

On the 2.0 branch a ClassCastException is logged in the server log file.
