[LAU] Spurious messages in jack_lsp output

Hello all,

I recently upgraded my Debian 'unstable' system (I know -- a terrible
thing to do to a functioning system), including a recent
version of the "jackd" package.

	jackd --version
	jackdmp 1.9.6

The package contains the utility program, jack_lsp,
which I rely on and need to be able to parse.

I find the STDOUT stream is peppered with what appear to be
debugging messages from the JACK server.

Is that purposeful or a bug?
