Description

Mark Paluch opened DATACASS-266 and commented

Cassandra list/set typed columns represent an empty collection as null. From here one can't tell whether the state was null or empty at the time saving the value. Loading this value causes MappingCassandraConverter to overwrite pre-initialized fields (e.g. with new ArrayList) with null.

Affects: 1.3.4 (Gosling SR4)
