JAXB 解组不适用于 JDK 1.6

Question

是的，这是一个冗长无聊的发布问题，同时可能非常简单。 :(

我只是从 Java 调用一个用 .NET 平台实现的 SOAP WebService 接口。收到数据后，使用 JAXB.Everything 将其转换为 java 对象在 JDK1.8 中运行良好，但在 JDK1.6

中失败

我注意到解组过程在 GetBjxsDataResponse 级别停止。也就是说，我可以从信封主体中成功获得 GetBjxsDataResponse 的实例，但是该实例的 getBjxsDataResult 成员为空。

这与JAXB RI 版本有关吗？我是 java 世界的新手。需要你的帮助！ :)

最后我选择用JAXM api and turn the result to Java object instance by Java reflection解析XML格式的响应。
