Problem with JMSXGroupFirstForConsumer

[Dris <ch...@hotmail.com>]

I am using message groups with 4.1.1 and NMS. I am finding that
JMSXGroupFirstForConsumer is not being set reliably for the first message
with a given groupId. I cannot as yet see any pattern in the failures. I
have tried just setting the groupId to i.ToString() in a loop for example
and after getting around 220 messages with JMSXGroupFirstForConsumer set, I
then start to receive every tenth one without it set. I have also tried
using GUIDs and the pattern of errors is understandably more random. I have
some test code I can post, but I was wondering if anyone else had observed
any similar behaviour. Messages do seem to be being delivered to consumers
correctly however, it is just that the first message in each group isn't
always flagged as such.

Just grab the MBeans from JMX?

EnqueueCounter doesn't seem to be counting correctly.

[Jim Alateras <ji...@comware.com.au>]

The TotalEnqueueCounter, in BrokerView class seems to be incrementing 
even when I don't send messages to the broker. Has anyone else 
experienced this. The dequeue and queued counters seem to be operating 
as expected.

Retrieving stats for a particular queue

Hi,

I can get the TotalXXXCounts statistics from the BrokerView but was 
wondering how I can retrieve the same stats for a particular queue.

Re: QueueSender question

[Adrian Co <ac...@exist.com>]

Create an anonymous sender by specifying a null destination in the 
createSender method and specify the actual destination in each send.

QueueSender question

[Jim Alateras <ji...@comware.com.au>]

If I create a QueueSender

QueueSender pub = session.createSender(new ActiveMQQueue("queue1"));

I can't seem to use it to publish to another queue.

pub.send(new ActiveMQQueue("queue2"), message);

when this executes i get the following exception

aused by: java.lang.UnsupportedOperationException: This producer can 
only send messages to: queue1


Is there any way i can use a single publisher to send messages to 
multiple queues.

cheers

Maybe something's gotten broken.

It'd be great to write up the code you're running as a JUnit test case
and add it to the distro to ensure this feature keeps working.
