XSLT transformation not working in 1.5 (but was in 1.4)

Question

Gentlemen,
I have a problem with some code that worked fine under 1.4 (at least up to 1.4.2_06), but now no longer works under 1.5.0 (I know this isn't the most recent, but I have yet to update).
I use the following XSL template in order to take a string containing a valid XML definition, strip out all whitespace (this is ok, I know I dont need it), and then indent it in a nice readable format.
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"  version="1.0" xmlns:xalan="http://xml.apache.org/xslt">
  <xsl:output method="xml" omit-xml-declaration="yes" indent="yes" xalan:indent-amount="2"/>
    <xsl:strip-space elements="*"/>
      <xsl:template match="@*|node()">
        <xsl:copy>
          <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
      </xsl:template>
</xsl:stylesheet>The code I use to perform the transformation is as follows :
// read the XML string into a DOM document structure
StringReader reader = new StringReader(xmlString);
InputSource source = new InputSource(reader);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(source);
// Input file to be transformed is the DOM document we have just created
Source input = new DOMSource(doc);
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(new StreamSource(new StringReader(TEMPLATE_AS_DEFINED_ABOVE)));
// create output writer and transform
StringWriter writer = new StringWriter();
transformer.transform(input, new StreamResult(writer));
System.out.println(writer.toString());As already stated, this produced the goods, in 1.4.2_06, but in 1.5.0 it results in the following error :

Answer 1

have you tried to remove the xalan specific entries
in the XSL and use that code:
transformer.setOutputProperty("{http://xml.apache.org/
xslt}indent-amount", "2");?Thanks for the reply.
Unfortunately, Ive already tried this, and it's not the problem.
If I remove the whole <xsl:template match /> section from the template, then the compilation error does not occur. I guess this narrows it down somewhat, but I don't know why that section is now failing under 1.5. (Ive since also tried with 1.5.0_03 - same error).
