> 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.
