Validating DocumentBuilder instance fails to parse more than one XML document.
------------------------------------------------------------------------------

         Key: XERCESJ-1101
         URL: http://issues.apache.org/jira/browse/XERCESJ-1101
     Project: Xerces2-J
        Type: Bug
  Components: JAXP (javax.xml.parsers)  
    Versions: 2.7.0, 2.7.1    
    Reporter: Vojtech Habarta
    Priority: Critical



When DocumentBuilder instance with W3C XML Schema validation is created using 
JAXP 1.2 and is used for parsing it fails on second XML document.

Here is sample code snippet:

    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    factory.setNamespaceAware(true);
    factory.setValidating(true);
    Object[] schemaSource = new Object[] {
        // it is important to pass schemas as InputStreams to prevent schemas 
reparsing
        ParsingTest.class.getResourceAsStream("ParsingTest.xsd"),
    };
    
factory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaLanguage";, 
"http://www.w3.org/2001/XMLSchema";);
    
factory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaSource";, 
schemaSource);
    DocumentBuilder documentBuilder = factory.newDocumentBuilder();
    documentBuilder.setErrorHandler(...);
    documentBuilder.parse(new FileInputStream("C:\\ParsingTest.xml"));
    System.out.println("OK");
    documentBuilder.parse(new FileInputStream("C:\\ParsingTest.xml"));
    System.out.println("OK");

When this code is run it throws this exception:

Exception in thread "main" org.xml.sax.SAXParseException: cvc-elt.1: Cannot 
find the declaration of element 'A'.

This code fail on Xerces 2.7.0 and 2.7.1. It works on Xerces 2.2.1, 2.3.0, 
2.4.0, 2.5.0, 2.6.0, 2.6.1 and 2.6.2. It also works on jaxp 1.2.2, jaxp 1.3.1 
and JDK 1.5.

This issue is very important for us because new validation API doesn't meet our 
performance requirements and requires JAXP 1.3 compatible parser (is less 
portable).
