public @interface JsonEnumDefaultValue

Marker annotation that can be used to define a default value used when trying to deserialize unknown Enum values.

This annotation is only applicable when the DeserializationFeature#READ_UNKNOWN_ENUM_VALUES_USING_DEFAULT_VALUE is enabled.

If the more than one enum value is marked with this annotation, the first one to be detected will be used. Which one exactly is undetermined.
