It is solution also when using @JsonFormat to parse date:

@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "dd.MM.yyyy HH:mm:ss") private Date scheduledTime;

when default constructor is not provided then default parser for date is used and default patterns (but are provided @AllArgsConstructor and getters/setters). What is interesting it works during serialization, but not during deserialization. If you want to avoid manual ObjectMapper configuration then provide default constructor for the class, I suppose that @Andreas answer is coupled also with this issue.
