Benjamin Lerer commented on CASSANDRA-13891:
--------------------------------------------
{quote}I have never used CircleCI before (the project is using this to build
and test C* right?), so I am lost about how to build and run the CI on my 2.2
patched branch.
I have created a CircleCI account via Github authentication, but it looks like
it tries to build a only master and even so it spews an error message. Could
you point me at links where I can find how to solve those issues?{quote}
Unfortunately, I cannot help you here. I always used our internal CI.
> fromJson(null) throws java.lang.NullPointerException on Cassandra

> 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.
