[ https://issues.jboss.org/browse/WFLY-7691?page=com.atlassian.jira.plugin.... ] Evandro Pomatti updated WFLY-7691: ---------------------------------- Steps to Reproduce: 1) Create a JMS Queue: {code:java} jms-queue add --queue-address=customQueue --entries=java:jboss/jms/customQueue {code} 2) Create a custom pool with a max-pool-size greater than the default (let's use 50): {code:java} /subsystem=ejb3/strict-max-bean-instance-pool=customPool/:add(max-pool-size=50,timeout=5,timeout-unit=MINUTES) {code} 3) Create a WAR application with an MDB and assign the annotation @Pool("customPool") to the MDB and also @ActivationConfigProperty(propertyName = "maxSessions", propertyValue = "50") to match the pool max size. Add a Thread.sleep to the onMessage() method to simulate. {code:java} @MessageDriven(name = "CustomMDB", activationConfig = { @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"), @ActivationConfigProperty(propertyName = "destination", propertyValue = "java:jboss/jms/customQueue"), @ActivationConfigProperty(propertyName = "maxSessions", propertyValue = "50") }) @Pool("customPool") public class DummyListener implements MessageListener { private static AtomicInteger count = new AtomicInteger(); @Override public void onMessage(Message message) { try { System.out.println("Count: " + count.incrementAndGet()); Thread.sleep(10000); } catch (InterruptedException e) { e.printStackTrace(); } } } {code} @Pool annotation needs the following dependency: {code:xml} <dependency> <groupId>org.jboss.ejb3</groupId> <artifactId>jboss-ejb3-ext-api</artifactId> <version>2.2.0.Final</version> <scope>provided</scope> </dependency> {code} 4) Deploy the application and send 50 messages to the queue. {code:java} @Stateless @Path("/enqueue") public class DummyResource { @Inject @JMSConnectionFactory("java:/JmsXA") private JMSContext context; @Resource(mappedName = "java:jboss/jms/customQueue") private Queue customQueue; @GET public void get() { IntStream.range(0, 50).forEach(i -> context.createProducer().send(customQueue, "message")); } } {code} Only 15 queue messages will be dequeue at a time, not the 50 that was specified in the pool. I also don't know why 15, since the default MDB pool is configured to be 20. was: 1) Create a JMS Queue: {code:java} jms-queue add --queue-address=customQueue --entries=java:jboss/jms/customQueue {code} 2) Create a custom pool with a max-pool-size greater than the default (let's use 50): {code:java} /subsystem=ejb3/strict-max-bean-instance-pool=customPool/:add(max-pool-size=50,timeout=5,timeout-unit=MINUTES) {code} 3) Create a WAR application with an MDB and assign the annotation @Pool("customPool") to the MDB and also @ActivationConfigProperty(propertyName = "maxSessions", propertyValue = "50") to match the pool max size.
