Question

当我尝试将我的webapp部署到Glassfish容器（静态shell和服务器）时，我对以下异常产生了一个真正的头脑。基本上，我有一个实体类，它具有以下属性：

    @Entity
    public class Anniversary implements Serializable, Comparable<Anniversary>
    {
     ...

        @Enumerated
        private AnniversaryType type;

     ....Rest of class
     }

它指的是声明如下的枚举类：

 public enum AnniversaryType

使用标准Maven项目在Netbeans 8.0中无需投诉即可构建程序，但在部署时会抛出以下异常：

Caused by: Exception [EclipseLink-7151] (Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd):         org.eclipse.persistence.exceptions.ValidationException

。我很困惑！我看了以下两个答案： JPA and enum type和jaxws and EclipseLink refuses to use enums from lib如果类在一个单独的jar文件中，它们都提供答案，但在我的情况下它不是（据我所知）。我在应用程序的其他地方确实遇到了另一个问题，我将其用作地图键，并且必须按照https://bugs.eclipse.org/bugs/show_bug.cgi?id=364922明确命名表和键值。

我完全被难过......任何帮助都会非常感激！

固定！问题是由枚举类中的以下行引起的：

return Arrays.asList(values()).stream().filter(type -> {
          return type.isCultural();
       }).collect(Collectors.toList());

我似乎遇到了在实体类中使用流的问题;当我使用它们时，它们似乎会引起各种明显不相关的例外。我已经向Glassfish提交了一份bug报告并等待他们的回复......

枚举不是枚举映射的有效类型
