Issue while sending InputStream to Server (POST)

Describe the bug

First, note that I cannot make a reproducer yet (I tries hard, but didn't find how to reproduce), and I cannot publish the code.

I tried with an example but didn't managed to show the error we've got (https://github.com/fredericBregier/quarkus-build-native-client-test/tree/main)

The issue is the following:

The server has an endpoint getting InputStream from a POST (using "Uni")
The client is using the QuarkusRestClientBuilder based on a Java interface for the Quarkus Rest client, but without Uni
If the Java interface is using InputStream too,
- using a filter extending ClientHeadersFactory (and @RegisterClientHeaders on it),
- having a response filter (using ResteasyReactiveClientResponseFilter and the associate @RegisterProvider),
- Then if we goes through QuarkusTest, everything run like a charm
- But if we start the server, then the client embedded in an app (both on different ports), so no more in test mode
- The client goes correctly to the query filter, logs, then the client stops without sending anything, until timeout occurs
  - The connexion is done (if we close the client, the server complains about it)
On the contrary, if we use byte array on client side only (letting server as is), then it works both on QuarkusTest and standalone tests

We have no idea on what's happens. This was reproducible on our OpenShift environement, setting the correct remote server url, but only byte array works, not InputStream

Any idea?

Expected behavior

There should not be any difference between client using InputStream or byte array

Actual behavior

On QuarkusTest, it works. But out of Quarkus test (standalone, openshift), only byte array works.

How to Reproduce?

Not able until now (except on our code)
