    Description

      Currently there are a few places that are not following the recommended pattern of using object mapper - reuse if possible. Actually we can use ObjectReader or ObjectWriter to replace the object mapper in some places: they are straightforward and thread safe.

      The benefit is all about performance, so in unit testing code I assume we don't have to worry too much.
