Consider the following java class:
import java.util.*;
import javax.xml.bind.annotation.*;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
            "fooObject"
        })
@XmlRootElement(name = "Foo")

public class Foo {
   protected List<Foo> fooObject;
   public List<Foo> getFooObject() {
       if (fooObject == null) {
           fooObject = new ArrayList<Foo>();
       }
       return this.fooObject;
   }
}
