Ali Alsuliman updated ASTERIXDB-2567:
-------------------------------------
    Description: 
When serializing a record, a field should be checked if it's nullable. The 
value to be serialized should be checked if it's null or value to serialize it 
correctly. Exceptions could happen when the record is in an array.

The below query produces an exception.

 
{code:java}
[{"f1": "fieldStr", "f2": 1 < "text"}] ;
result: exception, ANull cannot be cast to ABoolean
{code}
