JBossBytesMessage generates NullPointerException on 0-byte messages
-------------------------------------------------------------------

                 Key: JBMESSAGING-1281
                 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-1281
             Project: JBoss Messaging
          Issue Type: Bug
          Components: Messaging Core
    Affects Versions: 1.4.0.SP3
         Environment: JBoss 4.3.0GA on RHEL
            Reporter: Patrick Dolan
         Assigned To: Tim Fox
            Priority: Minor

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.
