升级到 Jersey 2.16 并尝试通过杰克逊支持基于角色的实体过滤的新功能。
NullPointerException被抛出：

如果我使用从抽象类继承的Jackson实体，有一个抽象方法可以重写某个自定义类的另一个对象。
JacksonFeature和SecurityEntityFilteringFeature已注册，资源方法如下：
@GET
@Produces(MediaType.APPLICATION_JSON)
@RolesAllowed(ACTUAL_ROLE)
public User getTestData() {
return new User("name", "address");
}
其中User被定义为：
public class User extends SuperUser {
private String name;
private String address;
public User(String name, String address){
this.name = name;
this.address = address;
}
public String getName() {
return name;
}
public String getAddress() {
return address;
}
@Override
public MoreData getMoreData() {
return null;
}
}
abstract class SuperUser {
public abstract MoreData getMoreData();
}
class MoreData {
}
一切正常如果getMoreData()返回例如String的非自定义异议。
知道这是否是杰克逊基于角色的实体过滤功能中的错误？
