Take into account Java Optional when calculating the property's required marker

[raderio]

class Data(val id: String, val email: Optional<String>)

email field is marked as required, but if we not pass data to it, it works correctly, it is initialized with Optional.empty.

Please mark Optional as non required.

@raderio jackson deserializes null or lack of the value as Optional.empty because it logically means absent of value. What's wrong with that?
