XML : Saxon xslt transformation is adding system properties to output

I am using Saxon HE and using it from command line. I am using the command mentioned in the documentation as

  java net.sf.saxon.Transform -s:source -xsl:stylesheet -o:output    

The transformation is working absolutely fine, except that the output file contains the list of all the java system properties before the actual content. I don't think I have anything special in my xslt. I am copying the first few lines here.

  <?xml version="1.0"?>  <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fn="http://www.w3.org/2005/xpath-functions">  <xsl:output method="xml" indent="yes"/>  <xsl:template match="/java/object/void[@property='testResults']">  <testsuites>    

Is there any clue why this could be happening?
