Description

With the following xml file:

<?xml version = "1.0" encoding = "UTF-8"?>
<a>
<l>
25</l>
<b>
<l>
25</l>
<p>
123</p>
</b>
<b>
<l>
50</l>
<p>
567</p>
</b>
</a>

and the following stylesheet:

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

<xsl:template match="/">
<xsl:apply-templates/>
</xsl:template>

<xsl:template match="a">
<xsl:apply-templates select = "b"/>
</xsl:template>

<xsl:template match="b">
<xsl:apply-templates select = "p"/>
</xsl:template>

<xsl:template match = "p">
<xsl:if test = "normalize-space(../l) = normalize-space(/a/l)">success</xsl:if>
</xsl:template>

<xsl:template match = "*"/>

</xsl:stylesheet>

the following error is produced:

(Location of error unknown)XSLT Error (java.lang.StackOverflowError): null

The following xml files do not cause the error to manifest:

<?xml version = "1.0" encoding = "UTF-8"?>
<a>
<l>25</l>
<b>
<l>
25</l>
<p>
123</p>
</b>
<b>
<l>
50</l>
<p>
567</p>
</b>
</a>

<?xml version = "1.0" encoding = "UTF-8"?>
<a>
<l>
25</l>
<b>
<l>25</l>
<p>
123</p>
</b>
<b>
<l>50</l>
<p>
567</p>
</b>
</a>

Suggesting that it only occurs when the content of at least one matched node on both sides of the equality test begins with a newline per run.
