Jackson XmlMapper Converting XML to POJO, node text's key is ""

Question

I'm trying to read in XML data from a service (and I cannot change the data) and having a problem with the Jackson XmlMapper. If I have XML like so:

<entry>
   <title type="text">W411638</title>
</entry>

It gives me back the following map:

title: ["": "W411638", "type": text]

I'm trying to turn this into an object using the following code:

XmlMapper xmlMapper = new XmlMapper()
Entry entry = xmlMapper.readValue(xmlData, Entry.class)

And my entry class looks like so:

class Entry {
    static class Title {
        //String __;  //-- This is what I can't figure out --
        String type; 
    }

    Title title;
}

The problem is I can't find any way of getting that title text ("W411638") into the entry object. The type pulls in fine and I can get it by doing entry.title.type and it's correct, I just don't know how to get that title value.

This works for me as a standalone Groovy Script...

@Grab( 'com.fasterxml.jackson.dataformat:jackson-dataformat-xml:2.0.5' )
import com.fasterxml.jackson.dataformat.xml.XmlMapper
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlText

class Entry {
  static class Title {
    public String type

    @JacksonXmlText
    public String value

    public String toString() {
      "$type -> $value"
    }
  }

  public Title title

  public String toString() {
    "Entry [$title]"
  }
}

def xml = '''<entry>
            |    <title type="text">W411638</title>
            |</entry>'''.stripMargin()

def xmlMapper = new XmlMapper()
Entry pojo = xmlMapper.readValue( xml, Entry )

println pojo // prints 'Entry [text -> W411638]'

Fingers crossed it works for you too!
