Невозможно построить экземпляр класса данных Kotlin, несмотря на использование Jackson-Module-Kotlin ⇐ JAVA

[Anonymous]

Я пытаюсь покинуть класс данных Kotlin, но я получаю ошибку: < /p>
Exception in thread "main" com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of `TestBean` (although at least one Creator exists): cannot deserialize from Object value (no delegate- or property-based Creator)

< /code>
Вот код: < /p>
fun main(args: Array) {
ObjectMapper().registerKotlinModule()
.readerFor(TestBean::class.java)
.readValue("{\"foo\": \"bar\"}");
}

data class TestBean(private val foo: String)
< /code>
и зависимости: < /p>
