resteasy-reactive client complains about server components missing

[maxandersen]

Describe the bug

I have a command mode app which when run tells me:

2021-08-21 02:29:55,190 ERROR [io.qua.run.Application] (main) Failed to start application (with profile prod): java.lang.RuntimeException: Resteasy Reactive server side components are not installed.

why are resteasy reactive server side parts required to do resteasy reactive client operations ?
