> I see. I'd say the most user friendly solution would be to create a new extension `camel-quarkus-jcache-caffeine` that would host this reflection registration plus it would depend on `quarkus-caffeine`. We should also add a hint to `extensions/jcache/runtime/src/main/doc/usage.adoc` that end users may want to depend on `camel-quarkus-jcache-caffeine` if they want to use caffeine as a jcache impl.

Start by reviewing pull request 4088 and the discussion linked from issue 1846. Inspect extensions/jcache/runtime/src/main/doc/usage.adoc and the existing JCache extension structure. Done means a new camel-quarkus-jcache-caffeine extension provides the requested reflection registration, depends on quarkus-caffeine, and documents that users may need it for Caffeine as a JCache implementation.
