Empty root tag deserialization bug

[Seatec13]

Hello,
I have a strange problem with jackson-databind 2.9.* (with 2.8.* everything work good):

Data class:

@Data
public class PackInstanceOrder {
    private Long orderId;
    private Long orderTypeId;
}

Simple test:

    @Test
    fun test() {
        val XML_OBJECT_MAPPER = XmlMapper()

        val xml = "<orders></orders>"
        val orders: List<PackInstanceOrder> = XML_OBJECT_MAPPER.readValue(xml,
            XML_OBJECT_MAPPER.getTypeFactory().constructCollectionType(List::class.java, PackInstanceOrder::class.java))

        assertThat(orders, notNullValue())
    }

throw an error:

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "" (class PackInstanceOrder), not marked as ignorable (2 known properties: "orderId", "orderTypeId"])
at [Source: (StringReader); line: 1, column: 18] (through reference chain: java.util.ArrayList[0]->PackInstanceOrder[""])

When adding @JsonIgnoreProperties(ignoreUnknown = true) annotation to PackInstanceOrder, error was changed:

com.fasterxml.jackson.databind.exc.MismatchedInputException: Unexpected end-of-input when binding data into PackInstanceOrder
at [Source: (StringReader); line: 1, column: 18] (through reference chain: java.util.ArrayList[1])

BUT! When I change xml to
<orders/>
test didn't throw any errors and pass well.
