> 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]): 
> {code}select intkey, objectvalue from smalla where intkey = 14 {code}
> Stack Trace:
