[xmlblaster] java.lang.NullPointerException in org.xmlBlaster.engine.dispatch.CbDispatchConnection.doSend

["Brad Clements" <bkc at murkworks.com>]

I have switched to version 1.3, enabled htpasswd authentication.

Now, my clients (which used to work), do not work, because xmlBlaster dies on 
the very first publish to my client. I am using socket protocol, non-ssl.

Log shows this::

ethereal shows that xmlblaster immediately closes the tcp connection, instead of 
sending the update message.

Any idea how I can trace this down?

Its the same setup as xmlblaster 1.2, except I enabled http authentication (in 
clients) and setup an htpasswd file.
