.forEach 和 .sort 不起作用，并且无法在块中设置断点

I am using Java 8 (build 1.8.0_25), Netbeans 8.0.2 and am incorporating some of the Java 8 features into an existing app. Sorting and .forEach is not working so I have created some test code to ensure I understand lambdas, etc. and to diagnose the problem. Below is a mix of new code as well as code to interact with the data from my system:

  public void test(Registration reg) {
/* new code */
    List<String> family = new ArrayList<>();
    family.add("Mom");
    family.add("Dad");
    family.add("Brother");
    family.add("Sister");

    family.forEach(p -> System.out.println(p));

    Collections.sort(family, (p1,p2) -> {
        System.out.println(p1 + " <==> "+ p2);
        return p1.compareToIgnoreCase(p2);
            });

    family.forEach(p -> System.out.println(p));

/* code to test with my system data */
    List<RegistrationItem> item = new ArrayList<>();
    List<RegistrationItem> regI = reg.getRegistrationItem();

    regI.forEach(p -> {
        System.out.println(p.toString());
        item.add(p);
            });

    Collections.sort(regI, (r1,r2) -> {
        System.out.println(r1.toString() + r2.toString());
        return r1.getId().compareTo(r2.getId());
    });

    for (RegistrationItem r : regI) {
            item.add(r);
    }
}

Registration 是一个 POJO，它反映了一个事件的数据，其中包括一个 RegistrationItem(s) 列表，它是另一个 POJO 的详细信息.在此测试中，列表大小为 4.
