Description
primitive wrapper types (integer, long, float, double, etc.) do not account for null values from Cassandra, but instead return their default 0 value. Teiid also throws NPE when Blob column contains null.
Query (should return [14,null]):
select intkey, objectvalue from smalla where intkey = 14
