Jms not working after update to spring boot 3 (and ConnectionFactory from javax to jakarta)

Question

After update from SpringBoot v.2.5.5 to v3.1.0 it was necessary to update also ConnectionFactory from javax.jms.ConnectionFactory to jakarta.jms.ConnectionFactory. I haven't changed anything else. Unfortunately now I'm getting an errors like this: ERROR - Could not refresh JMS Connection for destination 'tServerEvent' - retrying using FixedBackOff{interval=5000, currentAttempts=0, maxAttempts=unlimited}. Cause: Could not connect to broker URL: tcp://localhost:61616. Reason: java.net.ConnectException: Connection refused: no further information

I investigated it and compared with the old javax.ConnectionFactory and it seems that default brokerUrl for them is different

for javax.jms.ConnectionFactory it was : vm://localhost?broker.persistent=false for jakarta.jms.ConnectionFactory it is : tcp://localhost:61616

Even if I manually set broker url, like this:

spring:
  activemq:
    broker-url: vm://localhost?broker.persistent=false

it is not working still and the error is: Cause: Could not create Transport. Reason: java.io.IOException: Transport scheme NOT recognized: [vm]

I don't know why the default brokerUrl is different for jakarta.ConnectionFactory and old javax.ConnectionFactory and don't know how can I run my application succesfullt. I would appreciate if you have some tips for me.

And here is code with JmsListenerContainerFacroty Bean with ConnectionFactory:

import jakarta.jms.ConnectionFactory;
import org.springframework.boot.autoconfigure.jms.DefaultJmsListenerContainerFactoryConfigurer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jms.annotation.EnableJms;
import org.springframework.jms.config.DefaultJmsListenerContainerFactory;
import org.springframework.jms.config.JmsListenerContainerFactory;

@Configuration
@EnableJms
public class JmsConfig {

    @Bean
    public JmsListenerContainerFactory<?> myFactory(ConnectionFactory connectionFactory, DefaultJmsListenerContainerFactoryConfigurer configurer) {
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        configurer.configure(factory, connectionFactory);
        return factory;
    }

}

Support for ActiveMQ was removed in Spring Boot 3.0 as is did not support JMS 3.0 (the jakarta.jms.* APIs). Spring Boot 3.1 restored support for auto-configuring an ActiveMQ client. Embedded broker support has not been restored as ActiveMQ's broker does not yet support JMS 3.0.

To use ActiveMQ will Spring Boot 3.1, you will have to use an external broker as Spring Boot's ActiveMQ smoke test does.
