Tom White commented on AVRO-1455:
---------------------------------

Thanks for pointing that out Doug. Looks like there's no real conflict between 
the two patches though since it should always be safe to reuse immutable 
numeric primitive types.

> Deep copy does not need to create new instances for primitives

> optimization is already present for String.
