RESTEasy Reactive: empty 500 response when reader throws

Similar to #13797, if an exception occurs while reading stuff, the server throws a 500 with no body and doesn't print anything on stderr either, so the error is hidden from the user:

package org.acme.rest;

import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

class FroMage {
    public String name;
    // required for Jackson
    // public FroMage() {}
    public FroMage(String name) {
        this.name = name;
    }
    @Override
    public String toString() {
        return "Cheese: " + name;
    }
}

@Path("negotiated")
public class Endpoint {

    @Consumes(MediaType.APPLICATION_JSON)
    @PUT
    public FroMage putJson(FroMage fromage){
        return fromage;
    }
}

        <dependency>
            <groupId>io.quarkus</groupId>
            <artifactId>quarkus-resteasy-reactive</artifactId>
        </dependency>
        <dependency>
            <groupId>io.quarkus</groupId>
            <artifactId>quarkus-resteasy-reactive-jackson</artifactId>
        </dependency>

Now run:

$ curl -v --include -X PUT --data '{"name": "brie"}' --header 'Content-Type: application/json' http://localhost:8080/negotiated

You will get an empty 500.

The hidden exception is:
