> AMQMessage (the 0-9-1 path) caches message size, however
> MessageTransferMessage (the 0-10 path) does not. This means that the
> delivery path from AbstractQueue may require retrieval of the message meta
> data from the store to get the message size. Since not all requests to get
> the message size are protected by first getting a message reference, there is
> a chance of a race whereby the message is removed from the store between
> checking whether it is available and obtaining the message size.
