-----------------------------------------------------------
I've downloaded trunk, and while I am seeing the new, fixed exceptions, the
timing seems off. If the message that exceeds the queue size is message number
N, the exception appears to only get thrown when I send message number N+1.
For example, say queue limit is 100k, and the queue is current 99k. When I
send message N of 2k, no exception is thrown, even though it has exceed the
queue size limit and the message is rejected by the queue. Then, when I send
the next message (N+1) of 2k, the exception is thrown.
In contrast, the Python client seems to throw the exception at message number
N, which seems more intuitive to me.
Is this a bug in trunk?

> In JMS, when a message is sent when a queue is already at its maximum size,
> nothing happens for 60 seconds. The program just hangs there. Then,
> suddenly, these two exceptions are thrown:
> org.apache.qpid.transport.SessionException: timed out waiting for session to
> become open (state=DETACHED)
> at org.apache.qpid.transport.Session.invoke(Session.java:442)
> at
> org.apache.qpid.transport.SessionInvoker.messageTransfer(SessionInvoker.java:96)

> This is in contrast to, for example, a Python qpid producer, which will throw
> an exception as soon as the queue is full, and it will be very specific about
> the problem, telling you the queue is too full, which message overfilled it,
> etc.
> I tested this using a hacked up version of the direct producer/consumer JMS
> example. Just run the producer (without the consumer running) long enough
> with large enough messages so that it will reach the maximum queue size, and
> you should be able to see it.
