Description

Xalan issues a NullPointerException when I try to create a Transformer object for the following XSLT stylesheet:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/">
<xsl:for-each select="*" >
<xsl:sort select="a" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

The NullPointerException can be reproduced with the following command line executed in the Xalan install directory:

java -jar xalan.jar -XSL ftopic1861-NPE-in-Xalan.xsl

where ftopic1861-NPE-in-Xalan.xsl contains the above stylesheet. If I remove the xsl:sort/@xmlns:xsl attribute the NPE does not occur any more.
