Running fop 0.20.4RC with saxon.jar (instead of xerces+xalan) I got exception:

Font definition is <font
metrics-file="file:///d:/fop/fop-0.20.3/fonts/arial.xml" kerning="yes"
embed-file="d:/fop/fop-0.20.3/fonts/ttf/arial.ttf">

I believe the problem is due to the fact that metricsFile is stored in file name
form, rather than URI, and then FontReader is trying to parse metrics file using
the file name, which is not of course valid URI. Well, it works in xerces, but
Aelfred is more picky and expects URI according to sax specification.
