> When you call consumer->receive() on empty queue receive method returns NULL message but before return MessageConsumer::autoAcknowledge method is invoked. This method doesn't check message against NULL, this cause coredump is message is NULL.
> Patch: 
> p<IMessage> MessageConsumer::autoAcknowledge(p<IMessage> message)
> {
>     try
>     {
>         if ( message != NULL ) {   // <------ Check NULL here !!!!!
>           // Is the message an ActiveMQMessage? (throws bad_cast otherwise)
>           p<ActiveMQMessage> activeMessage = p_dyncast<ActiveMQMessage> (message) ;
>           // Register the handler for client acknowledgment
>           activeMessage->setAcknowledger( smartify(this) ) ;
>           if( acknowledgementMode != ClientAckMode )
>               doAcknowledge(activeMessage) ;
>         }
>     }
>     catch( bad_cast& bc )
>     {
>         // ignore
