SimpleXML parse ignores @Root name parameter

SimpleXML library has issue. It ignores @Root name. Here is code with test:

Class:

@Root(name = "res", strict = true)
@Data
@NoArgsConstructor
@AllArgsConstructor
class Response {

    @Attribute(name = "a")
    private Integer a;

    @Attribute(name = "i")
    private Integer i;

    @Attribute(name = "o", required = false)
    private Integer o;

}

Test:

    @Test
    public void detectXml() {

        Serializer serializer = new Persister();

        String xml = "<xxx a=\"1\" i=\"1\"/>";

        Response res = null;
        try {
            res = serializer.read(Response.class, xml);
        } catch (Exception e) {
            e.printStackTrace();
        }

        assertNotNull(res);

    }

Test passes no matter what is first tag in xml ie."<xxx" library ignores @Root name "res". Any suggestions beside to switch to another XML parser library? Can anyone suggest one with class annotations like SimpleXML?
