Subject Re: Some stomp-messages are received with an empty text
Date Wed, 25 Aug 2010 05:54:12 GMT
I vaguely remember seeing something similar, not sure if it was over XMPP or 
Stomp, but I was sending BytesMessages and the client got nothing.  I changed it 
to send TextMessage and all was OK.

Could this be your problem?
