ActiveMQ Artemis Transport scheme not recognized [vm] error

I tried to run this code:

EmbeddedActiveMQ server = new EmbeddedActiveMQ();
server.setConfiguration(new ConfigurationImpl()
        .setAcceptorConfigurations(singleton(new TransportConfiguration(
                InVMAcceptorFactory.class.getName())))
        .setPersistenceEnabled(false)
        .setSecurityEnabled(false));
server.start();

ConnectionFactory cf = new ActiveMQConnectionFactory("vm://0");
Connection connection = cf.createConnection();

But I got this exception:

javax.jms.JMSException: Could not create Transport. Reason: java.io.IOException: Transport scheme NOT recognized: [vm]

All I could find on the web suggested that I'm missing some dependency on the classpath, but none failed with the vm protocol.

If you run into this error and you're not using Apache Artemis, then make sure activemq-broker is on the classpath.

It turned out that I used a wrong import. I used:

org.apache.activemq.ActiveMQConnectionFactory

but I should have used:

org.apache.activemq.artemis.jms.client.ActiveMQConnectionFactory

For some reason the apache-artemis:2.10.1 includes dependency to activemq-client from activemq version 5, which includes the other class.
