Review comment:
       Can't do. See comment above. Logically I am operating here on the 
`AvroGenericRecordReader.reader`. I just need a temporary `nonFinalReader` 
instance variable so I can access the field in `catch` clause. Otherwise 
compiler would complain that field may not be initialized yet.
