I'm getting the following error when I start Jetty:

2010-03-01 12:30:19.328:WARN::Failed startup of context WebAppContext@15ddf5@15ddf5/webapp,null,/path/to/jetty-distribution-7.0.1.v20091125/webapps-plus/webapp.war

With this commandline:

java -jar start.jar OPTIONS=All lib=/path/to/jetty-distribution-7.0.1.v20091125/lib/ext etc/jetty.xml etc/jetty-plus.xml /path/to/webapp/src/configuration/test.xml

And test.xml contains:

<?xml version="1.0"  encoding="ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">
<Configure class="org.eclipse.jetty.webapp.WebAppContext">
  <Set name="contextPath">/webapp</Set>
  <Set name="war"><SystemProperty name="jetty.home" default="."/>/webapps-plus/webapp.war</Set>
</Configure>

If I don't include test.xml on the commandline it works fine.
