   public void addMethod(MethodDescriptor methodDescriptor) {
        methods.computeIfAbsent(methodDescriptor.getMethodName(), k -> new ArrayList<>(1))
                .add(methodDescriptor);

//        descToMethods.computeIfAbsent(methodDescriptor.getMethodName(), k -> new HashMap<>(1))

Have you changed your service in runtime?

[vio-lin]

yes，we need add common method in below process for legacy code 。

org.apache.dubbo.config.ServiceListener#exported

and return result with filter like ‘org.apache.dubbo.rpc.filter.GenericFilter’.

This scenario need to use re-export. However, re-export isn't well-tested on Triple~ :) Would you like to fix it?
