Main problem was having the nested classes as 'static.

import org.apache.tools.ant.Task;
import org.apache.tools.ant.types.DataType;

public class MyTask extends Task {
  // Hold a list of real Things-Objects. Not just Strings.
  private List<Things> things = new ArrayList<Things>();

  public void execute() {
    System.out.println("MyTask");
    for (Things t : things) {
       t.print();
    }
  }

  public void addThings(Things things) {
    this.things.add(things);
  }



  // Class must be marked as static for being accessible by the Runtime
  public static class Things extends DataType {
    private List<Thing> things = new ArrayList<Thing>();
    public List<Thing> getThings() {
        return things;
    }
    public void addThing (Thing f) {
       things.add(f);
    }
    private String language;
    public void setLanguage(String l) {
       language = l;
    }
    public String getLanguage() {

       System.out.println("- Things: language=" + getLanguage());
       for(Thing t : things) {
          t.print();
       }
    }
  }



  public static class Thing extends DataType {
    private String name = "";
    public void addText(String name) {
       Project p = getProject();
       // All nested elements can occur multiple times. So be prepared.
       this.name += p.replaceProperties(name);
    }
    public String getName() {
       return name;
    }
    public void print() {
       System.out.println(" -- Thing: text=" + getName());
    }
  }

}
