> In an attempt to fix the side effect of a problem CASSANDRA-13868 was
> committed in 2.2.11, 3.0.15, 3.11.1 and trunk.
> This patch introduced an issue on how empty values were rendered by {{SELECT
> JSON}} queries.
> Instead of returning the correct value for the type a null value was now
> returned.
> A user detected that problem for text column and opened CASSANDRA-14245 to
> request a fix for that problem. Unfortunately, I misunderstood the problem
> and the fix did not solve the real problem. It only made the code return 'an
> empty string instead of null values.
> The proper fix is to rollback the changes made for CASSANDRA-13868 and
> CASSANDRA-14245.
> Some unit tests also need to be added to test the behavior.
