/**
* Load a Json Object into a Java String property.
*
* This allows a Json object or array to be stored in a Java String property, without being escaped.
*
* Example: A department that has employees array, and we want to load into Java Dept, but have the Dept.employees just loaded into a String
* as json.
*
* NOTE: this is not needed in OAObjects, only POJOs.
* OAJacksonSerializer and Deserializer have this functionality built in, and dont require these annotations.
*
* Note: for Pojos, this requires using @JsonRawValue for the serialization so that it wont escape the String during serialization.
