### Bug description
When trying to user a Quarkus LangChain4j AI service by interface type as
below:
```
@RegisterAiService
@ApplicationScoped
public interface MyAiService {
@UserMessage("My Prompt")
@Handler
String chat(String question);
}
...
@Override
public void configure() {
from("...")
.bean(MyAiService.class);
}
```
Then, the stack trace below is produced:
```
