[jira] [Commented] (CASSANDRA-13891) fromJson(null) throws
java.lang.NullPointerException on Cassandra
[ https://issues.apache.org/jira/browse/CASSANDRA-13891?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16334909#comment-16334909 ]

--------------------------------------------
Hi [~marcel@lisemarie.com], and [~jdarcy], I am still finding my way again after a long period of absence from Cassandra dev, so I would like to see if I am missing something here. Thanks!

> Basically, {{fromJson}} throws a {{java.lang.NullPointerException}} when NULL is passed, instead of just returning a NULL itself. Say I create a UDT and a table as follows:
> {code:java}
> create type type1
> (
> id int,
> name text
> );
> create table table1
> (
> id int,
> t FROZEN<type1>,
> primary key (id)
> );{code}
> And then try and insert a row as such:
> {{insert into table1 (id, t) VALUES (1, fromJson(null));}}
> I get the error: {{java.lang.NullPointerException}}
> This works as expected: {{insert into table1 (id, t) VALUES (1, null);}}
> Programmatically, one does not always know when a UDT will be null, hence me expecting {{fromJson}} to just return NULL.
