`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.**
Using the same environment and code as yours, here are my reproduction
results:
```
$ curl -i 127.0.0.1:9080/get
HTTP/1.1 500 Internal Server Error
Date: Sat, 31 Jul 2021 12:40:19 GMT
Content-Type: text/html; charset=utf-8
Content-Length: 553
Connection: close
para-test: test
ETag: "610544ac-229"
Server: APISIX/2.7
```
the `para-test` header has been successfully returned to the client.
