> I've noticed that there are some netty resources remained in jvm when
> application is undeployed from app server (tested on Glassfish 7.0.18, Payara
> server 6.2024.8, Wildfly 33.0.2 Final)
> I have a code example copied from activemq-artemis-examples project.
> {code:java}
> private Session session;
> private MessageProducer producer;
> private ActiveMQConnection connection;
> private ActiveMQConnectionFactory connectionFactory;
>
> public void publish() {
> String activemqBrokerUrl =
> "tcp://localhost:61617?useGlobalPools=false&consumerWindowSize=0";
> String activemqUsername = "admin";
> String activemqPassword = "admin";
> try {
> connectionFactory = new
> ActiveMQConnectionFactory(activemqBrokerUrl, activemqUsername,
> activemqPassword);
> connection = (ActiveMQConnection)
> connectionFactory.createConnection();
> connection.start();
> session = connection.createSession(false,
> Session.AUTO_ACKNOWLEDGE);
> Queue queue = session.createQueue("jms/test");
> producer = session.createProducer(queue);
> ObjectMessage message = session.createObjectMessage();
> message.setStringProperty("Hello", "World");
> producer.send(message);
> producer.close();
> session.close();
> connection.close();
> connectionFactory.close();
> } catch (JMSException ex) {
> log.error("JMSException", ex);
> }
> } {code}
> (tried also to add FastThreadLocal.destroy() after connectionFactory.close()
> line)
