OK, now I see your problem - I missed the 'alsa' in your description

of an app connecting to Jack, and was assuming a Jack app making

unwanted connections. 
AFAICS, the syntax of the ALSA jack plugin specifies the ports to

connect to, and not the app's own ports which remain unknown. In

that case I don't see any solution. It's just bad design in the

sense that it missed a chance to be more general and configurable.
