使用Java RMI遇到一个奇怪的问题。 我有一个客户端服务器体系结构，其中单个客户端应根据可用性将消息调度到多个服务器实例。 为了进行通信，使用了RMI。启动服务器时，在JVM中运行的进程将启动RMIRegistry，随后又启动了多个服务器进程，并且在RMIRegistry中注册没有问题。

INFO  org.springframework.remoting.rmi.RmiServiceExporter - Binding service '##' to RMI registry:RegistryImpl_Stub[UnicastRef [liveRef: [endpoint:[192.168.165.218:1098](remote),objID:[0:0:0,0]]]] 

在给定时间之后，链接到RMI注册表的进程将停止，并开始新的进程。这些新进程将无法在RMI注册表中注册自己，说：
