Just so I get the setup correctly: do the font-locations vary with  
each rendering run? If not, and they always remain the same, it's  
better practice (will yield better performance, in general) to share  
the FopFactory between multiple sessions. You could then include its  
configuration in the same code-block where you instantiate the factory.

I see a possibility that this could indeed have an influence: static  
code can be compiled, inlined and executed as soon as the class is  
loaded. If the FopFactory is not configured to use auto-detection, the  
font-triplets referenced in the eventual target process will not be  
found in the cache, and FOP will fall back on a value of 'any'.

See above. I think all you need to do, is make sure that right after  
you instantiate the FopFactory, it is properly configured to auto-
detect OS installed fonts. If that still doesn't work, you'll have to  
activate debug-output, to check whether the referenced font was  
properly loaded.


HTH!
