GraalVM native error on micronaut-vertx-pg-client

[pjgg]

Expected Behavior

I would expect that dependency micronaut-vertx-pg-client add all the required GraalVM configuration in order to be able to compile/run my "micronaut-vertx-pg-client" application in native mode.

Actual Behaviour

Given a simple app with the following dependencies:

dependencies {
    implementation('com.ongres.scram:client:2.1')
    implementation("io.micronaut.sql:micronaut-vertx-pg-client")
    implementation("io.micronaut.rxjava2:micronaut-rxjava2")
    implementation("io.micronaut:micronaut-runtime")
    runtimeOnly("ch.qos.logback:logback-classic")
    implementation("io.micronaut:micronaut-inject")
    implementation ('io.micronaut:micronaut-management')
}

App:

package com.example;

import io.micronaut.http.MediaType;
import io.micronaut.http.annotation.Controller;
import io.micronaut.http.annotation.Get;
import io.micronaut.http.annotation.Produces;
import io.reactivex.Single;

import io.vertx.reactivex.pgclient.PgPool;
import io.vertx.reactivex.sqlclient.Row;
import io.vertx.reactivex.sqlclient.RowIterator;
import jakarta.inject.Inject;

@Controller("/postgres")
public class HelloWorldController {

    @Inject
    PgPool pgClient;

    @Get("/hello")
    @Produces(MediaType.TEXT_PLAIN)
    public String index() {
        return "Hello World";
    }

    @Get
    @Produces(MediaType.TEXT_PLAIN)
    public Single<String> getPostgresVersion() {
        return  pgClient.query("SELECT version()")
                .rxExecute()
                .map(rows -> {
                    RowIterator<Row> rowIt = rows.iterator();
                    if (rowIt.hasNext()) {
                        return rowIt.next().getString("version");
                    }

                    return "";
                });
    }
}

application.yml

micronaut:
  application:
    name: micronaut-demo
  server:
    port: 8080
vertx:
  pg:
    client:
      port: 5432
      host: localhost
      database: mydb
      user: user
      password: topsecret
      maxSize: 5

When I compile my app with GraalVM ./gradlew clean nativeCompile

native-image.properties

Args = --initialize-at-run-time=io.vertx.pgclient.impl.codec.DataTypeCodec \
       --trace-class-initialization=io.vertx.core.logging.LoggerFactory \
       --allow-incomplete-classpath \
       --enable-all-security-services \
       -H:IncludeResources=logback.xml|application.yml \
       -H:Name=rxjava-app \
       -H:Class=com.example.Application \
       -H:ReflectionConfigurationResources=${.}/reflection.json \
       -H:+ReportUnsupportedElementsAtRuntime

reflection.json

[
  {
    "name": "io.vertx.pgclient.impl.codec.DataTypeCodec",
    "allDeclaredConstructors": true,
    "allDeclaredMethods": true
  }
]

and then make a query to localhost:8080/postgres I am getting the following error:

.18:33:38.396 [vert.x-eventloop-thread-13] ERROR i.m.http.server.RouteExecutor - Unexpected error occurred: Could not initialize class io.vertx.pgclient.impl.codec.DataTypeCodec
java.lang.NoClassDefFoundError: Could not initialize class io.vertx.pgclient.impl.codec.DataTypeCodec

If I swap the graalVM config property initialize-at-run-time to initialize-at-build-time then I am getting the following compile error:

Caused by: com.oracle.graal.pointsto.constraints.UnsupportedFeatureException: No instances of io.vertx.core.logging.SLF4JLogDelegate are allowed in the image heap as this class should be initialized at image runtime. To see how this object got instantiated use --trace-object-instantiation=io.vertx.core.logging.SLF4JLogDelegate.

Because looks like pgClient internally is using a Log library that needs to be initialized at runtime but it also seems that DataTypeCodec needs to be initialized at build time, so looks like a chicken-egg problem

Steps To Reproduce

Just create a hello world app like this one:

package com.example;

import io.micronaut.http.MediaType;
import io.micronaut.http.annotation.Controller;
import io.micronaut.http.annotation.Get;
import io.micronaut.http.annotation.Produces;
import io.reactivex.Single;

import io.vertx.reactivex.pgclient.PgPool;
import io.vertx.reactivex.sqlclient.Row;
import io.vertx.reactivex.sqlclient.RowIterator;
import jakarta.inject.Inject;

@Controller("/postgres")
public class HelloWorldController {

    @Inject
    PgPool pgClient;

    @Get("/hello")
    @Produces(MediaType.TEXT_PLAIN)
    public String index() {
        return "Hello World";
    }

    @Get
    @Produces(MediaType.TEXT_PLAIN)
    public Single<String> getPostgresVersion() {
        return  pgClient.query("SELECT version()")
                .rxExecute()
                .map(rows -> {
                    RowIterator<Row> rowIt = rows.iterator();
                    if (rowIt.hasNext()) {
                        return rowIt.next().getString("version");
                    }

                    return "";
                });
    }
}

and try to compile with GraalVM and make a Query to /postgres
