Summary: QueueBrowser fails to select messages

Initial Comment:
From [email protected] to the openjms-user 
list:

The following sample doesn't properly work if the 
number of messages in
queue exceeds 20.

QueueBrowser browser=qs.createBrowser
(qs.createQueue("edition"),
"JMSMessageID = '"+id+"'");
java.util.Enumeration listeMsg = 
browser.getEnumeration(); 
int i=0;
while (listeMsg.hasMoreElements()) {
 Message message = (Message)
listeMsg.nextElement(); 
  if (message != null) {
      System.out.print(i++);
      System.out.println("
'"+message.getJMSMessageID()+"'");
  } else {
      break;
  }
}

This was being caused by a bug in 
QueueBrowserEndpoint.receiveMessages() method.
This gets supplied a count of messages to fetch. If none 
of the first count messages examined matched the 
selection criteria, it would return an empty list, 
signifying no matching messages. 
It now returns iff:
. up to count messages match the selection criteria; or
. all messages have been examined

Fix will be available in the 0.7.6 release.
