Misleading exception message in Starter

           Summary: Misleading exception message in Starter
           Product: Fop
           Version: all
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: general
        AssignedTo: fop-dev@xml.apache.org
        ReportedBy: elharo@metalab.unc.edu


In org.apache.fop.apps.Starter, the setParserFeatures() method
is as follows:

 public void setParserFeatures(XMLReader parser) throws FOPException {
  try {
    parser.setFeature("http://xml.org/sax/features/namespace-prefixes",
     true);
  } catch (SAXException e) {
    throw new FOPException("Error in setting up parser feature namespace-prefixes\n"
     + "You need a parser which supports SAX version 2", e);
  }
}

The exception message is potentially incorrect and misleading.
While all SAX2 parsers must recognize the 
http://xml.org/sax/features/namespace-prefixes property, they are
*not* required to support a true value for this property. The
default is false, and that is all a SAX2 parser is required to
support. A more appropriate error message would be:

"You need a parser which allows the 
http://xml.org/sax/features/namespace-prefixes feature to be set
to true"
