> In both EJB client and server code, on method invocations where context data is sent, the sender writes the attachment count as a packed integer but the reader consumes it as an unsigned byte.  This is not good.
> The fix:
> * In protocol 3 and higher, always read and write a packed integer
> * In protocol 2 and lower, always read a packed integer but write a signed byte, failing if more than 127 attachments are present
> Note that this is only temporary in the WFLY project as the server code should ultimately be moving to live in the ejb-client library.
