public T getNullValue(DeserializationContext ctxt)
JsonDeserializer
JsonToken.VALUE_NULL
). Usually this is simply
Java null, but for some types (especially primitives) it may be
necessary to use non-null values.
This method may be called once, or multiple times, depending on what
JsonDeserializer.getNullAccessPattern()
returns.
Default implementation simply returns null.
