---------------------------------------

             Summary: server side ClassCastException using compact storage
                 Key: CASSANDRA-6813
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6813
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Paul Kendall


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

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

USE test ;

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

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

UPDATE lock USING TTL 10 SET owner=null WHERE partition='a' AND key='b' IF owner=null;
{code}

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