Strange results with CSSimpleFile getInputStream

I am trying to use the Content Services API within a JSP page. The JSP page reads an XML configuration file (stored within the backing store) and then sets options appropriately in the page. When the getInputStream method is used, strange exceptions are getting thrown, indicating a problem reading data. If the physical path to the file in the backing store is used instead, the XML parses correctly and the page works fine, leading me to conclude that the XML document is fine. Also, I used Internet Explorer to open the XML document, and it too parsed it successfully.

Here is the snippet:
CSClient client = (CSClient)request.getAttribute( "iw.csclient");
CSVPath vCfgFile = new CSVPath(request.getParameter("vpath") + "/config/preview.xml");
CSSimpleFile csConfigFile = (CSSimpleFile) client.getFile(vCfgFile);

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();

Document document = builder.parse( csConfigFile.getInputStream(false) );

// This works if uncommented
//Document document = builder.parse( "Y:/default/main/WORKAREA/Component/config/preview.xml" );

This is the exception being thrown:
javax.servlet.ServletException: The processing instruction target matching "[xX][mM][lL]" is not allowed.
at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:536)

What am I doing wrong?

Forgot to add one other thing. I checked what was coming out of the input stream using the following snippet of code:
<%
BufferedReader readFromFile = new BufferedReader(new
InputStreamReader(csConfigFile.getInputStream(false)));
String nextLine;
int counter = 1;
while ((nextLine = readFromFile.readLine()) != null) {
%>
<%= counter %>:<%= nextLine %>
<%
counter++;
}
%>

and everything seemed to look correct. For whatever reason, the XML parser is dying.
