Clay,
that's almost spooky. It almost appears as if the file system cache is
malfunctioning on your system since it's not recognizing if a file is
replaced. I'm very confident when I'm saying that FOP itself has no
means to cache anything if you're starting FOP from the command-line for
each file you're processing. The only entity that is then capable of
showing this behaviour is a faulty file system cache. But that seems to
be unlikely. The only thing now coming to my mind is that you might be
holding your logos on a remote file system like NFS or via SMB. If you
do, try working on a local harddrive to see if it behaves differently.
You're using relative URLs. You're not getting the logo from a webserver
via HTTP or something, right? But even if you do, I couldn't explain why
your system still appears to be caching the logos.
I could be wrong about some of this but it sounds real strange. Maybe
someone else has a better idea about what's going on.
