> Sometimes we get sent zero-byte BytesMessages through our system via user error or other and when such a message is read by JBoss Messaging and converted into a JBossBytesMessage object, a NullPointerException occurs.  The source of the error is in the checkRead method:
> bais = new ByteArrayInputStream(payloadAsByteArray);
> In this case the payloadAsByteArray object is not initialized since the message was empty and the BAIS throws a NullPointerException.  This is certainly not a high-priority issue but it might be better to either check that condition or throw a more meaningful JMS exception when empty messages are encountered.
