FOP 0.93: Cannot load fonts/NullPointerException

I’m using the DocBook 1.72 XSL stylesheets with FOP 0.93.
I followed the Apache FOP instructions for regenerating font metrics files, and
I updated the FOP configuration file to the new format. When I run FOP, I get
the following exception.

 

SEVERE: Exception

java.lang.RuntimeException: Cannot load font:
failed to create Source from metrics file SY______.xml

 

It didn’t seem to be loading any of the fonts. The <font-base>
in the configuration file was correct, so I don’t know why it couldn’t
load the files. I decided to update the configuration file to use relative URLs
based on the <base>. When I ran FOP again, I got a NullPointerException:

Any idea what could be wrong?
