@JsonPropertyOrder not respected with defined attributes

[thrykol]

I've noticed that attributes in a POJO must be included first in the @JsonPropertyOrder annotation list in order for the other properties to be ordered.

It is my understanding that the properties in the ordered list take precedence while unlisted properties will follow the ordered properties in any order.

I am using version 2.3.1 from maven central.

In the test class

public class OrderTest
{
    private String a = "first";
    @JacksonXmlProperty(isAttribute = true)
    private String b = "attribute";
    private String c = "second";

    public static void main(String[] args)
        throws Exception
    {
        XmlMapper xmlMapper = new XmlMapper();
        xmlMapper.configure(SerializationFeature.INDENT_OUTPUT, true);
        xmlMapper.writeValue(System.out, new OrderTest());
    }

    public String getA()
    {
        return a;
    }

    public String getB()
    {
        return b;
    }

    public String getC()
    {
        return c;
    }
}

annotating the class with either @JsonPropertyOrder({"a", "c"}) or @JsonPropertyOrder({"a", "c", "b"}) results in orderless output while the annotation @JsonPropertyOrder({"b","a", "c"}) orders properly.

Interesting. It does sound like a bug; partial ordering should be fine.

Yes, I can reproduce the issue, and added a unit test.

Simple bug, fixed for 2.3.2. Thank you for reporting this!
