Bug in Xalan2.0.0 ?

[Carsten Ziegeler <cz...@sundn.de>]

Hi,

we have sometimes problems with the Xalan2.0.0.

Occasionally it throws the following exception during processing "node()" in this template:

<xsl:template match="node()|@*"><xsl:copy>
	<xsl:apply-templates select="node()|@*"/> <!-- this line is the source of the exception -->
</xsl:copy></xsl:template>

java.lang.NullPointerException

        at java.lang.Thread.run(Thread.java:484)

The exception occurs only sometimes, after reprocessing the xml it disappears for a while.

We use Xalan2.0.0 in Cocoon2. It seems that the error only occurs during processing of frames,
when several requests are send to Cocoon2 and Xalan has to process these parallel requests.

Is there anything wrong with our template or is this a bug?
