Java HazelcastSerializationException依赖于操作系统

最近我收到了一些关于HZ的奇怪错误。序列化/反序列化。我有一台装有hazelcast服务器的Windows服务器。在我在Linux机器上运行的测试中，我可以通过HazelcastClient API连接到Hazelcast服务器，注册SerializationFactory并从HZ服务器获取一些集合。 我使用简单的IdentifiedDataSerializable接口来序列化/反序列化实体。 实体由3个字段组成：字符串、整型、整型

结果我得到HazelcastSerializationException。这是因为Windows和Linux机器之间的差异吗

这就是测试用例：

Igor，你能提供Hazelcast版本和完整的异常跟踪吗。谢谢哦，对不起。我忘了堆栈跟踪中有一些有趣的东西，比如“com.hazelcast.nio.serialization.HazelcastSerializationException:java.io.eofeexception:无法读取4字节！”
