PathParam containing "/" character are not well encoded as "%2F" when using reactive rest client with Stork

[Jojal]

Describe the bug

I need to call an external API from my Quarkus backend.
For this example, the external api is like this : http://localhost:8081/api/v1/path/{pathParam}
With in my case "pathParam"=/x/y/z

When using the reactive rest client, everything is working well and my external API give me a 200.

As soon as i add the stork extension to retrieve the URL of the external API, i got a 404 error from my external API.
Stork is used only to retrieve "http://localhost:8081" as the base url.

If i understand well, when using reactive rest client without stork everything is ok because the called url is :
http://localhost:8081/api/v1/path/x%2Fy%2Fz (with "/" character correctly encoded)

When i do the same with stork, the url is well resolved (http://localhost:8081) but the url called is :
http://localhost:8081/api/v1/path/x/y/z (with "/" character not encoded as "%2F"

I will try to give a reproducer later if needed. Not easy to extract it actually because it's part of a big project.

Expected behavior

The expected behaviour would be to have the "/" (or others) well encoded when using stork extension.

Actual behavior

Actuel behavior is the "/" character as a PathParam is not well encoded only when using stork extension. It work's well when using the reactive rest client without Stork.

How to Reproduce?

To reproduce :

• Call an external API that contains "/" character in path param. (http://localhost:port/api/v1/path/{pathParam} with pathParam=/x/y/z
• With reactive rest client and without stork -> http response is 200
• With reactive rest client + stork -> http response is 404
