Thanks.. Yes, it's better solve it within type.toJSONString
I will add test the specification of type.toJSONString. all should not change
buffer position.

While adding test cases for DurationType, I found following error, maybe
related to
[cassandra-11873|https://issues.apache.org/jira/browse/CASSANDRA-11873]
{code}
CREATE KEYSPACE ks WITH replication = {'class': 'SimpleStrategy',
'replication_factor': 1};
CREATE TABLE ks.cf ( key text PRIMARY KEY , d duration );
// following CQL will fail, due to `JSON_OBJECT_MAPPER.readValue(json,
Object.class);` returning `-2`
INSERT INTO ks.cf (key , d ) VALUES ( '22', fromJson('-2h1m'));
// following CQL will pass, value of duration is taken from the json map of
`JSON_OBJECT_MAPPER.readValue(json, Map.class);`
INSERT INTO ks.cf JSON '{ "key":"111", "d":"-2h9m"}';
{code}
