> Key: XALANJ-2347
> URL: http://issues.apache.org/jira/browse/XALANJ-2347
> Project: XalanJ2
> Issue Type: Bug
> Components: Xalan
> Affects Versions: 2.7
> Environment: Win XP, Xalan Java 2.7.0, java.version=1.5.0_06
> Reporter: Robert Eaton
> Assigned To: Henry Zongaro
> Priority: Minor
>
> I have been getting a StackOverflowError when trying to perform an XSL
> transformation using Xalan 2.7.0 with a styleshhet I had written. I have
> simplified the the XSL and the problem seems to be related to an xpath
> expression used in an if, but I can't see anything wrong with it.
> I was using this xml:
> <?xml version="1.0" encoding="UTF-8"?>
> <docdef>
> <region name="Main Region">
> <section id="2" name="section1">
> <frag id="1" name="part1" type="text">
> <p style="body" align="left" xml:space="preserve">first paragraph.</p>
> </frag>
> <frag id="2" name="next fragment" type="text">
> <p style="inherit" align="center" xml:space="preserve">Paragraph with a style
> of inherit but its own alignment , first in fragment.</p>
> <p style="inherit" xml:space="preserve"/>
> <p xml:space="preserve">Another paragraph</p>
> </frag>
> </section>
> </region>
> </docdef>
> with this xsl:
> <?xml version="1.0" encoding="UTF-8"?>
> <xsl:stylesheet version="1.0"

> <xsl:template match="[EMAIL PROTECTED]'inherit']">
> <xsl:if test="not(preceding-sibling::*) or preceding-sibling::*[1] !=
> preceding-sibling::p[1]">
> <w:p>
> <w:pPr>
> <!-- This is the problem statement. The error does not occur if the '@align
> or' is removed from the start of the xpath.-->
> <xsl:if test="@align or
> preceding::p[not(ancestor::table)][not(@style='inherit')][1]/@align">
> <xsl:element name="w:jc">

> The error message I get from Xalan is
> (Location of error unknown)XSLT Error (java.lang.StackOverflowError): null
> Exception in thread "main" java.lang.RuntimeException
> at org.apache.xalan.xslt.Process.doExit(Process.java:1153)
> at org.apache.xalan.xslt.Process.main(Process.java:1126)
> If I do the transformation within XMLSpy it does not report any errors so it
> seems to be something to do with Xalan.
> I have tried enabling various tracing options, see output below, but I get no
> additional output.

> I have also managed to get the error with a different but similar Xpath
> expression. It seems to be a problem when it starts with "@align or
> preceding" an attribute test followed by the ancestor axis does not seem to
> cause a problem and if I remove the '@align or' from the begining and break
> it up into multiple xsl:if statements it is okay.
> I believe it is happening when the stylesheet it first passed before it
> actually starts the transformation.
