That warning was added to JACK version 0.50.0 (IIRC).  It is just a
warning.  The jack_set_buffer_size_callback() function is not invoked,
and in fact never was.  The purpose of the message is to inform
developers not to use this function.

When newer versions of your applications are released, the message
will go away.  Meanwhile, just ignore it.  It should not cause a
problem connecting.  So, iiwusynth must be encountering some other
problem.
