#84 Exception "Unable to read categories.xml file" when loading XsltTransformer

[Anonymous]

Hi,

I recently updated to Saxon-HE 9.8.0-1 from Saxon-HE 9.4.0.1 and I am getting an exception when attempting to load one of the spreadsheets that I was using before.

I have tracked down the issue to the following stylesheet (simplified use case to reproduce the error, I know the stylesheet makes no sense as is):

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema" 
    xmlns:test="http://test"
    exclude-result-prefixes="xs test" 
    version="2.0">

    <xsl:function name="test:getFontName" as="xs:string">
        <xsl:variable name="fontName" select="tokenize(' abc', '\s*,\s*')[1]"/>
        <xsl:value-of select="$fontName"/>
    </xsl:function>

</xsl:stylesheet>

The Java code that I'm using to create the transformer is taken from the examples:

Processor proc = new Processor(false);
XsltCompiler comp = proc.newXsltCompiler();
XsltExecutable exec = comp.compile(new StreamSource(new File("validator.xsl")));
XsltTransformer trans = exec.load();

The exception message I get is:

Can you help me figure out what the issue is and how to solve it?
