           Summary: Font metrics-url and embed-url are aways absolute, fails
                    without good error message
           Product: Fop
           Version: 1.0dev
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: P2
         Component: pdf renderer
        AssignedTo: fop-dev@xmlgraphics.apache.org
        ReportedBy: ken.blackler@jrc.it


Under 1.0 the metrics-url and embed-url attribites of the <font> element are 
not relative to the specified base directory. 

Therefore they are loading from the working directory of the process (which is 
usually c:\windows\system32 if your server is running as a windows service).

Under 0.20 one was able to call:

org.apache.fop.configuration.Configuration.put
("fontBaseDir","/absolute/path/to/metrics/directory");

or put this in your configuration file.

Is is possible to add a way to specify a base directory for the font metric 
files, or make them relative to the configuration file itself. Otherwise one 
needs to encode system specific paths in the configuration file.

Also, this fails silently at the moment, and later on throws a null pointer 
error. Logging of the failure to load a metric file is labelled as todo. Since 
this is going to be a common error, a meaningful message will save users hours 
of trying to figure out what is happening....

Attached is a patch file to log a meaningful error. Also I have moved the flag 
of successfull loading so that the flag is only set if they are really loaded.

Should the exception propogate up rather than swallowing it?
