Error when desirializing the result of serialization

[Hunsu]

I have a strange problem with deserializing xml into a POJO. I have this test:

    @Test
    public void testSerializeMovies() {
        Movie m1 = new Movie("tt12547", "The Hobbit", 2005);
        Movie m2 = new Movie("1254", "Title", 2007);
        List<Movie> movies = new ArrayList<Movie>();
        movies.add(m1);
        movies.add(m2);
        Movies root = new Movies(movies);
        String expected = "<root>"
                + "<movie imdbID=\"tt12547\" title=\"The Hobbit\" year=\"2005\"/>"
                + "<movie imdbID=\"1254\" title=\"Title\" year=\"2007\"/>"
                + "</root>";
        System.out.println(mapper.writeValueAsString(root));
        assertEquals(expected, mapper.writeValueAsString(root));
        root = mapper.readValue(expected, Movies.class);
        System.out.println(root);
    }

The serialisation works fine but when I try to deserialize the obtained xml I get this error:

    com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: 
    Unrecognized field "movie" (class org.m1.iaws.pcws.model.Movie),
    not marked as ignorable (3 known properties: "title", "imdbID", "year"])

When I do the desrialization of this xml:

    <root response="True">
        <movie title="The Hobbit" year="1977" imdbID="tt0077687" />
    </root>

I get the same error about response attribute even though response is part of the root element not the movie element. Normally response is member of the class Movies not Movie so why I get the error?

Unrecognized field "response" (class org.m1.iaws.pcws.model.Movie), not marked as ignorable

Could you also include definition of Movie and Movies classes? I can not reproduce behavior without those.

    @JsonCreator

    public String getError() {
        return error;
    }

    @JsonProperty("error")
    public void setError(String error) {
        this.error = error;
    }

    public void setResponse(boolean response) {
        this.response = true;
    }

    public String toString() {
        return movies.toString();
    }
}

Test case now passes in that deserialization succeeds (although exact XML output differs somewhat, not sure if that is problematic or not). I suspect the problem was same as #177 (and/or possibly #167).
Either way, fixed for 2.7.0 or 2.6.5, both to be released in near future.
