Serializing string with escaped double quotes to XML

I have a problem trying to serialize a Java Object to XML using jackson XmlMapper.

One of the fields contains a string with escaped double quotes, like this:

String example = "This is a string with \"escaped double quotes\"";

When i pass object to XMLmapper (variables is the object containing example string):

  XmlMapper xmlMapper = new XmlMapper();
  String xml = xmlMapper.writeValueAsString(variables);

this is the output i get:

some other tags
<example>This is a string with "escaped double quotes""This is a string with "escaped double quotes""This is a string with "escaped double quotes"</example>
some other tags

How can i serialize a string with escaped doubled quotes to XML achieving proper result, i.e.

<example>This is a string with "escaped double quotes"</example>

Then: "Sorry, cannot reproduce"!

</project>

src/main/java/com/example/xml/mapper/SimpleBean.java:

@Data

    final String example = "This is a string with \"escaped double quotes\"";
}

public class Main {

    public static void main(String[] args) throws JsonProcessingException  {
        XmlMapper xmlMapper = new XmlMapper();
        String xml = xmlMapper.writeValueAsString(new SimpleBean());
        System.out.println(xml);
    }
}

... >mvn clean package exec:java -Dexec.mainClass=com.example.xml.mapper.Main (jdk8), prints:

...
