JMS broker does not acknowledge messages in EAP 7.2.2

Solution Verified - Updated -


  • I have a load-balancing cluster consisting of two JBoss EAP 7.2.2 nodes. I sent a large TextMessage to the destination but the JMS broker did not acknowledge the message. This is causing the JMS broker to pile messages that have already been consumed. However, the broker acknowledged the message when I used JBoss EAP 7.1.5 or JBoss EAP 7.2 client library. Here's the onMessage() of my JMS client code:
    public void onMessage(Message message) {
        try {
            System.out.println("MSG " + message.getBody(String.class));
        } catch (JMSException e) {
