I get a NullPointerException when running this test file:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

xmlns:myxsl="http://www.myxsl.com">

<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>

<xsl:namespace-alias result-prefix="xsl"/>

</xsl:stylesheet>

Here is the stack dump:
