IMHO this is not the case with the TTFReader. It tells you about each file 
it reads and writes. If you convert a couple of files at once this is a 
little inconvenient. Maybe it should have a silent mode? BTW if you embed 
the TTF Reader i would prefer getting exceptions when something goes wrong 
rather than geting null return (and a stack trace in stdout)

Re: Changing logging behavior in an embedded application.

Hmm, FOP does not do anything special with warning messages as opposed
to debug- or info-level messages. If you managed you reroute all logging
to java.util.logger it's a matter of configuring that thing correctly.
FOP does have a few System.out.println calls in its source code but
these are only in places where those are ok, i.e. in command-line
handling code. Your other post about the Verdana font showed that you're
not calling FOP's command-line so everything does go through the logging

Did you specify a logging config file using 
and properly set up the handlers?
