> AMQP defines as shortstr as a 1-octet length followed by that many octets of
> data. In java we use the AMQShortString class to represent this datatype in
> the 0-8/0-9 codebase. Unfortunately the AMQShortString class does not check
> to ensure that on construction its total length is less than 256 characters.
> In cases where an overlong AMQShortString is created and subsequently
> encoded, the size is written out as (byte) length, which means that a String
> of length 296 will be encoded as an octect with value 40 (296 & 255) followed
> by 296 octets of data. Upon decoding this causes a frame decoding error.
> We should check on construction of an AMQShortString that the underlying data
> does not have length > 255, and that if it does we should throw an
> appropriate exception (IndexOutOfBoundsException?)
> [This error was discovered when a long queue name was created, and that queue
> subsequently used as the destination for a reply-to field... the encoding of
> a reply-to copies the queue name twice (once as the queue name, once as the
> binding-key]
