[jboss-jira] [JBoss JIRA] (WFLY-10555) The list-messages and remove-messages don't work on a queue when consumer is connected

[Josef Cacek (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-10555?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13590453#comment-13590453 ] 

Josef Cacek commented on WFLY-10555:
------------------------------------

The consumer code is similar to:

{code:java}
try (JMSConsumer consumer = context.createConsumer(destination)) {
    while (true) {
        String text = consumer.receiveBody(String.class, waitTime);
        Thread.sleep(waitTime);
    }
}
{code}

Do I undertand it correctly the {{createConsumer()}} call buffers bunch of messages without knowing how many of them is the consumer able to receive?
And once the consumer is closed, are the messages released/returned to the queue on the server?
Is there any option to say I don't want to buffer messages, but I want to receive them one by one? (e.g I want to create more consumers running in parallel on a single queue.)
