> When a schema/protocol is written and read back in (see attached example) via Protocol.parse, the field ordering is not guaranteed to be preserved because the "Props" object extends HashMap, which has no ordering contract.
> Recommend switching to a Map implementation with an ordering guarantee.
> (Identified in Avro 1.5.1 - please verify against 1.5.4)
