Hazelcast-KRYO序列化集成问题-->；java.lang.LinkageError:尝试为名称复制类定义：

我正在尝试将KRYO序列化与Hazelcast集成，但由于以下错误而未能成功

当映射初始化时，会发生错误。有人能解释一下吗

也许一些代码会有所帮助

不久前，我为hazelcast添加了一个Kryo序列化程序，我没有遇到问题：

您好，我使用了与上述相同的方法。。但在初始化映射时失败。。不确定这是否是由于任何并发性造成的，因为我有几个由map store impl支持的映射，并在启动时加载映射。您好，很抱歉响应延迟。是的，我使用了与您发布的相同的代码..刚刚替换为我的对象引用。其他信息：AgreementVO的类型为Serializable，有10个成员变量，其中一个是自定义类型/类（实体），我们是否应该注册该类？是否要注册所有引用的类，这些类是需要序列化的对象的一部分？关于此错误可能原因的任何提示？好的，您只需要注册根类。
