fail to load plugin config dynamically at the second time

[lilai23]

What happened?

After dynamically installing a plugin and unstalling it, try to install the plugin again then throws ClassCastException
2024-05-22 16:10:37.191 [ERROR] [io.sermant.core.plugin.service.PluginServiceManager] [initPluginServices:59] [Attach Listener] Error occurs while starting plugin service: class io.sermant.monitor.service.report.MetricServiceImpl java.lang.ClassCastException: io.sermant.monitor.config.MonitorServiceConfig cannot be cast to io.sermant.monitor.config.MonitorServiceConfig at io.sermant.monitor.service.report.MetricServiceImpl.start(MetricServiceImpl.java:45) at io.sermant.core.plugin.service.PluginServiceManager.initPluginServices(PluginServiceManager.java:56) at io.sermant.core.plugin.PluginManager.doInitPlugin(PluginManager.java:203) at io.sermant.core.plugin.PluginManager.executeInit(PluginManager.java:188) at io.sermant.core.plugin.PluginManager.initPlugins(PluginManager.java:175) at io.sermant.core.plugin.PluginManager.install(PluginManager.java:81) at io.sermant.core.command.PluginsInstallCommandExecutor.execute(PluginsInstallCommandExecutor.java:44) at io.sermant.core.command.CommandProcessor.process(CommandProcessor.java:77) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at io.sermant.premain.AgentLauncher.executeCommand(AgentLauncher.java:153) at io.sermant.premain.AgentLauncher.launchAgent(AgentLauncher.java:93) at io.sermant.premain.AgentLauncher.agentmain(AgentLauncher.java:72) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at sun.instrument.InstrumentationImpl.loadClassAndStartAgent(InstrumentationImpl.java:386) at sun.instrument.InstrumentationImpl.loadClassAndCallAgentmain(InstrumentationImpl.java:411)

How can we reproduce it (as minimally and precisely as possible)?
