Re: Problem with example code, but just in Eclipse ?

Okay, I solved this.  I was actually being kind of dense on this one...

Batik actually does throw exceptions even when everything is okay.
The JVM keeps a file (fontconfig?) that maps abstract font names to
*potentially* available physical font names, and also the file system
path where they *might* be found.

When Batik searches through the entries in the file, it there's an
exception each time it's dealing with a font which doesn't exist on
the filesystem at the expected path.  But this is not a fatal error.

Anyway, when I ran my Batik-using code in Ecplipse, the debugger did a
breakpoint every time an exception was thrown, even these innoccuous
exceotions.  It never dawned on my that it might be okay for this to
happen.  I wasn't seeing this when I ran my program manually from the
command line, because I wasn't trapping the throwing of exceptions.
