ClassNotFoundException for Mp-RestClient Interfaces since Quarkus Version 2.8.2

Hi,
I’m using Camunda with Quarkus.

Since I have updated the camunda-bpm-quarkus-engine to Version 7.18.0-alpha2 and Quarkus to Version 2.8.2.Final I have a classloading problem. When I try to call an Microprofile RestClient interface from an asynchronous service-task I get a ClassNotFoundException for my interface.
When I change my service-task to synchronous everything works fine.
This behavior appears only in Quarkus-Mode dev and test. When I start my Quarkus-App in production-mode everything works fine.

Hi,
I’ve updated 2.5.4.Final Quarkus to 2.8.2.Final and Camunda engine to 7.18.0-alpha2 I’ve experienced same classloading issue described above. Additionally I’ve tried to update Quarkus to 2.10.0.Final but the same ClassNotfoundException appeared as in Quarkus 2.8.2.Final.
