   So generating the following file during the project generation `src/main/resources/reflection-config.json`:
   ```json
   [
     {
       "name" : "java.lang.String",
       "allPublicMethods" : true
     }
   ]
   ```
   And adding the `quarkus.native.additional-build-args=-H:ReflectionConfigurationFiles=reflection-config.json` build property works:
   
   ```console
   $ kamel run examples/languages/routes.yaml --logs
   Integration "routes" created
   Condition "IntegrationPlatformAvailable" is "True" for Integration routes: astefanu/camel-k
   Integration routes in phase "Initialization"

   The native build time seems stable around 4m30s:
   
   ```console
   $ kubectl get builds.camel.apache.org
   NAME                       PHASE       AGE     STARTED   DURATION          ATTEMPTS
   kit-c43s8si2qa460fs1tumg   Succeeded   4m53s   4m53s     4m28.894542898s 
   ```
   
   The `reflection-config.json` build configuration file could be generated based on language inspection. Also, it seems there is no need for `quarkus.camel.native.reflection.include-patterns` in that case.
