Jackson XML marshal error when XmlAttribute and XmlElement have the same name

Jackson XML appears not to be able to marshal a XML having a tag with a certain attribute whose name is also being used for the nested children tags (“occ”, in the following case).

<root>
    <txt occ="1">
        <occ id="1">first element</occ>
        <occ id="2">second element</occ>
    </txt>
    <txt occ="2">
        <occ id="1">first element</occ>
        <occ id="2">second element</occ>
    </txt>
</root>

Changing the name of the XmlAttribute “occ” or of the XmlElement “occ” makes it work.

This is how I’ve annotated my Txt Class:

@XmlAccessorType(XmlAccessType.FIELD)
public class Txt {

@XmlAttribute(name="occ")
private String occ_attr;

@XmlElement(name="occ")
private List<Occ> occ = new ArrayList<Occ>();

//getters and setters not annotated

And this is how I’ve annotated the Occ class:

public class Occ {

@XmlAttribute
private String id;

@XmlValue
private String value;

//getters and setters not annotated

Answer

Apparently it’s an issue of the library. As of today, the issue hasn’t been solved yet:
