(newbie) Xalan XSLTC problem

Question

Hi all,
I'm using latest versions of jdk and xalan-j, if try to transform the following xml+xsl with XSLTC
<?xml version="1.0" encoding="UTF-8" ?>
<root>
     <XWC:surname xmlns:XWC="http://www.something.it/XWC/2.0">
          Jones
     </XWC:surname>
</root>
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:XWC="http://www.something.it/XWC/2.0">
<xsl:output method="html"/>
<xsl:template match="XWC:*">
     <xsl:element name="{name()}">
          <xsl:apply-templates/>
     </xsl:element>
</xsl:template>
</xsl:stylesheet>
I get the following exception:
ERROR: ''

Exception in thread "main"
It works well usign interpretative Xalan or if I change the output-method to "xml".
Any help will be appreciated!

A clue: it doesn't throw an exception if the output-method is 'xml' instead of 'html'...
