    protected final com.fasterxml.jackson.databind.util.LRUMap<com.fasterxml.jackson.databind.type.ClassKey, QName>
    _rootNames
    For efficient operation, let's try to minimize number of times we need to introspect root element name to use.
    static final QName
    ROOT_NAME_FOR_NULL
    If all we get to serialize is a null, there's no way to figure out expected root name; so let's just default to literal "null".
