Reflection-free serializers generated but not used by Jackson #47571
Description
Describe the bug
I tried to enable reflection-free serializers in a project. The serializers are generated but not used by Jackson.
With some debugging info, I found that io.quarkus.resteasy.reactive.jackson.runtime.serialisers.GeneratedSerializersRegister.MappingModuleHolder#createMappingModule is invoked before io.quarkus.resteasy.reactive.jackson.runtime.ResteasyReactiveServerJacksonRecorder#recordGeneratedSerializer.
Expected behavior
Serializers are generated and used by Jackson
Actual behavior
Serializers are generated but not used by Jackson
How to Reproduce?
https://github.com/TechEmpower/FrameworkBenchmarks
Update this file: frameworks/Java/quarkus/resteasy-reactive-hibernate-reactive/src/main/resources/application.properties
Add:
quarkus.rest.jackson.optimization.enable-reflection-free-serializers=true
quarkus.package.jar.decompiler.enabled=trueYou can comment out quarkus.datasource.username, quarkus.datasource.password, quarkus.datasource.reactive.url and %dev.quarkus.datasource.reactive.url so that, on startup a dev services starts a database for you.
Then populate the DB with http :8080/createData (using HTTPie).
Finally, query an endpoint with http :8080/db
If you add breakpoints to the io.quarkus.benchmark.model.World, you will notice that when Jackson serializes it, it uses reflection.
