How to reproduce:

Migrate to RestEasy Reactive - git revert 428f579b1e86abe4181240d200504d850740844e
Build to native using mvn clean package -Dnative

Set the following env vars:

export TOKEN=test
export QUARKUS_DATASOURCE_USERNAME=admin
export QUARKUS_DATASOURCE_PASSWORD=mysecretpassword
export QUARKUS_DATASOURCE_JDBC_URL=jdbc:postgresql://localhost:5432/postgres

Start a PostgreSQL DB (I'm using Docker on M1)

docker run -it --name some-postgres -p 5432:5432 -e POSTGRES_USER=admin -e POSTGRES_PASSWORD=mysecretpassword -e POSTGRES_DB=postgres arm64v8/postgres

Start the application:

target/quarkus-registry-app-999-SNAPSHOT-runner

Populate the database running the script in https://github.com/quarkusio/quarkus-extension-catalog/blob/main/publish_local.sh
Open http://localhost:8080/client/platforms

quarkusio / registry.quarkus.io

Native application fails with NoSuchMethodException when RestEasy Reactive is used #99
