Error: Unsupported method java.net.NetworkInterface.isLoopback0(String, int) is reachable: Native method in Artemis JMS client

[gastaldi]

I can't use the org.apache.activemq:artemis-jms-client dependency directly because it fails with the following error when creating the native image:

Error: Unsupported method java.net.NetworkInterface.isLoopback0(String, int) is reachable: Native method. If you intend to use the Java Native Interface (JNI), specify -H:+JNI and see also -H:JNIConfigurationFiles=<path> (use -H:+PrintFlags for details)
To diagnose the issue, you can add the option --report-unsupported-elements-at-runtime. The unsupported element is then reported at run time when it is accessed the first time.

You have to enable JNI as specified in the error message. Via Gradle this is done by --enable-jni, via Maven by <enableJni>true</enableJni>. Also you need the following reflect config:

[
  {
    "name" : "org.apache.activemq.artemis.api.core.client.loadbalance.RoundRobinConnectionLoadBalancingPolicy",
    "allDeclaredConstructors" : true,
    "allPublicConstructors" : true
  }, {
    "name" : "org.apache.activemq.artemis.core.remoting.impl.netty.NettyConnectorFactory",
    "allDeclaredConstructors" : true,
    "allPublicConstructors" : true
  }
]

I can confirm that the quarkus-artemis-jms extension fixes the problem. Here is a sample REST endpoint illustrating how I tested it:

package org.acme;

import javax.inject.Inject;
import javax.jms.ConnectionFactory;
import javax.jms.JMSContext;
import javax.jms.Queue;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("/hello")
public class GreetingResource {

    @Inject
    ConnectionFactory connectionFactory;

    @GET
    @Path("/produce")
    @Produces(MediaType.TEXT_PLAIN)
    public String produce() {
        try (JMSContext jmsContext = connectionFactory.createContext()) {
            Queue teste = jmsContext.createQueue("TEST");
            jmsContext.createProducer().send(teste, "HELLO JMS WORLD!");
        }
        return "Published";
    }

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String consume() {
        String message = null;
        try (JMSContext jmsContext = connectionFactory.createContext()) {
            Queue teste = jmsContext.createQueue("TEST");
            message = jmsContext.createConsumer(teste).receiveBodyNoWait(String.class);
        }
        return message;
    }
}
