Simple Jackson XML deserialization to Java not working

I am hoping someone can point out what is escaping me. This is my first attempt to deserialize XML. Here is a cut-down of my problem.

Thanks,

Harold

I have these Java classes

@JacksonXmlRootElement(localName = "migrationCompatibility")
public class MigrationCompatibility {

    @JsonCreator public MigrationCompatibility() {}

    @JacksonXmlProperty(localName = "products")
    @JacksonXmlElementWrapper(useWrapping = false)
    public Products[] products;

    public Products[] getproducts() {
        return products;
    }

    public void setproducts(Products[] products) {
        this.products = products;
    }
}

public class Products {
    @JsonCreator public Products() {}

    @JacksonXmlProperty(localName = "foo")
    public String foo = "hi";

    public String getFoo() {
        return foo;
    }

    public void setFoo(String foo) {
        this.foo = foo;
    }
}   

And this code to test them.

Products products = new Products();
Products[] productsList = new Products[1];
productsList[0] = products;

MigrationCompatibility migrationCompatibility1 = new MigrationCompatibility();
migrationCompatibility1.setproducts(productsList);

XmlMapper xmlMapper = new XmlMapper();
xmlMapper.writeValue(new File("J:\\stuff.xml"), migrationCompatibility1);
MigrationCompatibility migrationCompatibility = xmlMapper.readValue(new File("J:\\stuff.xml"), MigrationCompatibility.class);
System.out.println(migrationCompatibility);

The serialization works as expected and produces the xml as expected. cat stuff.xml

<migrationCompatibility><products><foo>hi</foo></products></migrationCompatibility>

However the complementary call deserialize above results in an exception. It seems it does not recognize the tag, but I cannot not figure out why.

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "products" (...), not marked as ignorable (0 known properties: ]) at [Source: J:\stuff.xml; line: 1, column: 35]
