Describe what problem you have encountered
RocketMQ Client support run in GraalVM environment. it can't run now. You can reproduce this issue by following these steps：
Prerequisites Start RocketMQ broker and nameserver

1. Download the Spring Cloud Alibaba project, switch to the 2022.x branch, enter the rocketmq-broadcast-producer-example module, enter the pom.xml file, add below dependency and plugin.

<dependency>
   <groupId>com.alibaba</groupId>
   <artifactId>fastjson</artifactId>
   <version>2.0.22</version>
</dependency>

<plugin>
 <groupId>org.graalvm.buildtools</groupId>
 <artifactId>native-maven-plugin</artifactId>
 <configuration>
   <classesDirectory>${project.build.outputDirectory}</classesDirectory>
   <metadataRepository>
     <enabled>true</enabled>
   </metadataRepository>
   <requiredVersion>22.3</requiredVersion>
   <buildArgs>
     --initialize-at-build-time=org.apache.commons.logging.LogFactoryService
   </buildArgs>
 </configuration>
 <executions>
   <execution>
     <id>add-reachability-metadata</id>
     <goals>
       <goal>add-reachability-metadata</goal>
     </goals>
   </execution>
 </executions>
</plugin>

3. Execute mvn clean -Pnative spring-boot:run. After the application starts, it will scan the code dynamic properties. After about 10 seconds, stop the application through control+C, and there will be a META-INF.native in the resources directory. image directory, there will be a static configuration file corresponding to the dynamic properties of the code below. You need to enter the reflect-config.json file to delete the corresponding item of org.springframework.integration.config.ConverterRegistrar$IntegrationConverterRegistration.
4. Execute mvn clean -Pnative native:compile to build the native image. If it goes well, it will be built successfully, and then target/rocketmq-broadcast-producer-example should start the application and the problem should be reproduced.

It seems like your client can not connect to the nameserver. Please try nc 127.0.0.1 9876 -zv to check if the nameserver is running.

No, I confirm that the nameserver and broker is running, I can send message in general method.

@steverao The auto-scan of the reflection classes should be incomplete, check out the log output, there should be some ClassNotFound exceptions raised.

Check the client log

[steverao]

ClassNotFound

yes, there are a lot of relevant ClassNotFound warning logs when I use mvn clean -Pnative native:compile to compile the demo, it's hard to find which one cause the sending message error. Do you have any suggestion to help me solve it?
