Cassandra throws unknown error while creating column family through CLI or Astayanx client

I am trying to use chunked object store of cassandra and when I am trying to create compatible column family for the same, using CLI or Astyanax client, it throws this error:

My CLI command is:

CREATE COLUMN FAMILY updatedstorage WITH comparator = UTF8Type AND key_validation_class=UTF8Type;

Astayanax code is:

keyspace.createColumnFamily(CF_STANDARD1, ImmutableMap.<String, Object>builder()
                .put("default_validation_class", "UTF8Type")
                .put("key_validation_class", "UTF8Type")
                .put("comparator_type", "UTF8Type")
                .build());

Cassandra version: 1.1.7

Could you please help understanding what is the problem, everytime I run it, it goes to JVM dump ... :(
