Question

我正在运行hazelcast 3.6.3，当我运行以下时没有配置：

Hazelcast.newHazelcastInstance();

我得到如下例外：

java.lang.IllegalArgumentException: [class java.util.LinkedList] serializer cannot be overridden!
at com.hazelcast.internal.serialization.impl.AbstractSerializationService.safeRegister(AbstractSerializationService.java:331)

at com.hazelcast.core.Hazelcast.newHazelcastInstance(Hazelcast.java:87)
...

我没有注册任何序列化程序，当我降级到3.5.3时，同样的代码也能正常工作。我是否需要做任何改变配置的事情？

noctarius是对的。这是由Spring Boot打包jar中的两个版本的hazelcast.jar文件引起的。

由于Serializer覆盖，Hazelcast实例在启动时失败
