request help: I would like to know if this plugin supports the use of two or more interceptors simultaneously in a single jar？

### Issue description
I would like to know if this plugin supports the use of two or more interceptors simultaneously in a single jar？
I have two custom services that need to be placed in a custom plugin, but I found that an API gateway cannot support two or more custom plugins at the same time. Therefore, I want to put my current two services in one Java plugin. I have tested it and it seems that this feature is not supported. How can I solve this problem? Thank you very much for your answer.（我有两个自定义的服务需要放到自定义插件中，但是我发现一个apisix网关无法同时支持两个以上的自定义插件，所以我想把我目前的两个服务放到一个java插件中，我测试了，好像不支持这个功能，请问这个如何解决呢？非常感谢回答。）

### Environment
arm64 Open jdk 11
* your apisix-java-plugin-runner version
