Generic JSON data that stores all unknown key name/value pairs.
Subclasses can declare fields for known data keys using the Key annotation. Each field
can be of any visibility (private, package private, protected, or public) and must not be static.
null unknown data key names are not allowed, but null data values are allowed.
Implementation is not thread-safe. For a thread-safe choice instead use an implementation of
ConcurrentMap.
Sets the given field value (may be null) for the given field name. Any existing value
for the field will be overwritten. It may be more slightly more efficient than #put(String, Object) because it avoids accessing the field's original value.
Overriding is only supported for the purpose of calling the super implementation and
changing the return type, but nothing else.
