TransformerException does not include SAXParseException location info

When creating a Transformer from TransformerFactory.newInstance() by passing a
StreamSource of XSLT, a TransformerException is thrown, but does not include any
location information.

By exploring the TransformerException using this bit of code, I saw there was a
SAXParseException that contained location information:

boolean known = true;
while (known && (t != null)) {
    if (t instanceof TransformerException) {
        known = true;
        log4j.debug("Analysing known exception: " + t.getClass().getName());
        log4j.debug("getLocationAsString(): " + ((TransformerException)
t).getLocationAsString() + "");
        t = ((TransformerException) t).getCause();
    } else if (t instanceof org.xml.sax.SAXParseException) {
        known = true;
        log4j.debug("Analysing known exception: " + t.getClass().getName());
        int col = ((org.xml.sax.SAXParseException) t).getColumnNumber(); 
        int line = ((org.xml.sax.SAXParseException) t).getLineNumber();
        log4j.debug("Location: Col=" + col + ", line=" + line);
        t = ((org.xml.sax.SAXParseException) t).getException();
    } else {
        log4j.debug("Unknown cause: " + t.getClass().getName());
        known = false;
    }
}

Note: If you don't use log4j, replace "log4j.debug" by "System.out.println", for
example.

The result of this exploration gives:

Analysing known exception: javax.xml.transform.TransformerConfigurationException
getLocationAsString(): null
Analysing known exception: javax.xml.transform.TransformerConfigurationException
getLocationAsString(): null
Analysing known exception: javax.xml.transform.TransformerException
getLocationAsString(): null
Analysing known exception: org.xml.sax.SAXParseException
