> If a message takes the straight through delivery path through the Broker (that is, where
the IO thread that accepts the message from the publisher is the same thread that delivers
the message to the consumer), and the send to the consumer fails with exception (for instance,
a sender timeout exception), the connection to the consumer is rightfully closed. However,
when the consumer reconnects, the Broker sends the message to the consumer successfully, but
will suffer an "Unable to find message with id"  store exception when the consumers tries
to or ack the message/commit.
> The issue is that mishandling of the sendertimeout exception has meant the the Broker
has failed to perform *publishing* post delivery tasks so the message is never committed to
disk.
> Reproduction
> # Prepare a JMS publisher application that sends one message, make message sufficiently
large to overwhelm the TCP buffers (I use 100MB).
> # Prepare a JMS consumer application to receive the message.
> # Start the JMS consumer application, once it has begun to await the message (MessageConsumer.receive())
either stop the process or put a breakpoint in IoReceiver#run line 160)
> # Start the JMS publisher, it will send the message to the Broker
> # Broker will choose the straight through path
> # Broker's send to consumer will timeout (stack 1 below)
> # JMS consumer will be disconnected
> # Restart the JMS consumer
> # Expected behave message delivered to consumer successfully.  Actual behaviour, Broker
reports exception when client tries to ack the message (stack 2 below)
> stack 1 - Broker reports timeout on send to consumer
