Apache Dubbo Component

Dubbo Version
Dubbo Java 2.7.23,openJdk 1.11
Steps to reproduce this issue
1 CustomDispatcher implements Dispatcher and implements the related methods. 2 In the META-INF/dubbo directory, create a new file with the name org.apache.dubbo.remote.Dispatcher, with the content custom=com.xx.xx.CustomDispatcher 3 Call ProtocolConfig's setDispatcher method to set it to custom: protocolConfig.setDispatcher("custom") 4 start Provider sucessfully 5 When starting the consumer, it encounters the no provider error, and when tracing it through the debug, I found that when creating the NettyClient object, it calls org.apache.dubbo.remote.transport.dispatcher.ChannelHandlers#. wrapInternal -> ExtensionLoader.getExtensionLoader(Dispatcher.class) .getAdaptiveExtension() can't find the class CustomDispatcher and gives error PS: This error is not encountered when the Dispatcher's implementation class is changed to the built-in configuration.
What you expected to happen
The client-side Dispatcher should not be bound strictly and consistently to the server-side. If this is the case, there is no way to optimise the server-side Dispatcher schema when the client-side code is unable to make a task change that needs to be done

You'd better not to customize dispatcher
thanks,I accept your suggestion. I just customize a dispatcher that extends MessageOnlyDispatcher and makes a few changes about RejectedExecutionException. It does't affect the main process of MessageOnlyDispatcher. So,how should I do? @AlbumenJ
