`request.setArg("test_arg", "test_value");` means that rewrite the current
request, take a look at:
https://github.com/apache/apisix-java-plugin-runner/blob/main/docs/en/latest/development.md#rewrite-request
`response.setHeader("para_test", "test");` means that stop the current
request, the client will receive the relevant parameters generated here. take a
look at:
https://github.com/apache/apisix-java-plugin-runner/blob/main/docs/en/latest/development.md#stop-request
**If both of these exist, then the request will be stopped.**
the `config.yaml` of apisix:
```
ext-plugin:
cmd: ['java', '-jar', '-Xmx4g', '-Xms4g',
'/root/IdeaProjects/apisix-java-plugin-runner/runner-dist/apisix-runner-bin-dist/target/apisix-runner-bin/apisix-runner-bin/apisix-java-plugin-runner.jar']
```
log of successful jar startup output in apisix's `error.log`:

Using the same environment and code as yours, here are my reproduction
results:
