----------------------------------
Fix Version: 2.7
> XSLTC: exsl:node-set gives null pointer exception when casting a string to a
> text node
> --------------------------------------------------------------------------------------
>
> Key: XALANJ-1869
> URL: http://issues.apache.org/jira/browse/XALANJ-1869
> Project: XalanJ2
> Type: Bug
> Components: XSLTC
> Versions: 2.5Dx
> Environment: Operating System: Windows XP
> Platform: PC
> Reporter: Daniel Neades
> Assignee: Yash Talwar
> Fix For: 2.7
> Attachments: Patch.txt
>
> According to the documentation at
> http://www.exslt.org/exsl/functions/node-set/,
> the exslt node-set function should be able to turn a string into a text node.
> Thus, the following stylesheet should be legal:
> <?xml version="1.0" encoding="utf-8" ?>
> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
> xmlns:exsl="http://exslt.org/common";>
> <xsl:output method="xml" encoding="US-ASCII" />
> <xsl:template match="/">
> <xsl:variable name="text">Some text</xsl:variable>
> <xsl:apply-templates select="exsl:node-set($text)" />
> </xsl:template>
> </xsl:stylesheet>
> However, an attempt to execute this stylesheet with XSLTC (from Xalan 2.6.0)
> causes a NullPointerException:
> ERROR: ''
> <?xml version="1.0"
> encoding="US-ASCII"?>javax.xml.transform.TransformerException:

> With the Xalan 2.6.0 interpretive processor, this stylesheet causes a
> stackoverflow exception. I'm not quite sure why. Change the template's
> match="/"
> attribute to something like match="dx:element", and it works as expected with
> the interpretive processor (although it still gives a NullPointerException
> with
> XSLTC). Perhaps I'm missing something obvious?
> Further background information: the source document that I'm using to
> reproduce
> this is passed to the stylesheet as a DOMSource, built with Xerces.
