Different behavior entity resolver Xerces 2.11.0 and Xerces 2.10.0

[carla.spruit]

Hi,

When parsing an XML document "personal-schema.xml" with 
xsi:noNamespaceSchemaLocation="personal.xsd" with the code below, I get 
different systemId parameter values in the LSResourceResolver in version 2.11.0 
and 2.10.0 :

    DOMImplementationLS implementationLS = new DOMImplementationImpl();
    LSParser builder = 
implementationLS.createLSParser(DOMImplementationLS.MODE_SYNCHRONOUS, null);

    LSResourceResolver resolver = new LSResourceResolver() {

      public LSInput resolveResource(String type, String namespace, String 
publicId,
          String systemId, String baseURI) {
        // in Xerces 2.11.0, systemId is expanded: 
'file:/C:/my/path/to/doc/personal.xsd'
        // in Xerces 2.10.0, the value is exactly the same as declared in the 
document: 'personal.xsd'
        return null;
      }
    };

    builder.getDomConfig().setParameter("validate", Boolean.TRUE);
    builder.getDomConfig().setParameter("resource-resolver", resolver);
    Document doc = builder.parseURI(getURL("personal-schema.xml").toString());

Is this a bug?

Thanks!
