The result is a * map from property names (method name stripped of the get prefix and converted * to lower case) to property values. Property values are normalized through the * serializer. * * The denormalization first looks at the constructor of the given class to see * if any of the parameters have the same name as one of the properties. The * constructor is then called with all parameters or an exception is thrown if * any required parameters were not present as properties. Then the denormalizer * walks through the given map of property names to property values to see if a * setter method exists for any of the properties. If a setter exists it is * called with the property value.
