Deserialization of value classes with single private constructor

[kronst]

For some reason in 2.20.0 version deserialization of objects that contains value class with single private constructor now throws exception. I found a workaround how to fix this, but wondering if this is an issue or it was intended?

Simple example to reproduce the issue:

class ValueDeserializationTest {

    @Test
    fun testWrapperDeserialization() {
        val mapper = jacksonObjectMapper()
        val wrapper: Wrapper = mapper.readValue("""{"data":"test"}""")
        assertEquals("test", wrapper.data.value)
    }

    data class Wrapper(val data: Data)

    @JvmInline
    value class Data private constructor(val value: String) {
        companion object {
            fun create(value: String): Data {
                return Data(value)
            }
        }
    }
}

This works properly on 2.19.2 version. But after upgrading to 2.20.0 I got the exception during deserialization:

member is private: com.example.unit.ValueDeserializationTest$Data.constructor-impl[Ljava.lang.Object;@834e986/invokeStatic, from class com.fasterxml.jackson.module.kotlin.InternalCommonsKt (unnamed module @517d4a0d)

This could be fixed by adding @JsonCreator + @JvmStatic annotations to companion function. But is this really the only way to fix this?

companion object {
    @JvmStatic
    @JsonCreator(mode = JsonCreator.Mode.DELEGATING)
    fun create(value: String): Data {
        return Data(value)
    }
}
