[jaxrs-spec][quarkus] Feat: Add an option to use "org.jboss.resteasy.reactive.RestResponse" (#21877)

cmoine-swi · web-flow · commit ee4cb9ac228b · 2025-09-14T17:11:06.000+08:00
* replace Response by RestResponse

* fix rest response for Async

* update documentation

* Add option "returnJBossResponse"

* Add tests + fixes

* Polish

* Add dependency "io.quarkus.resteasy.reactive:resteasy-reactive" when returnJBossResponse=true

* fix JavaJAXRSSpecServerCodegenTest

* generate samples &amp; docs
