> 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
> Assignee: Michael Glavassevich
> Priority: Critical
> Attachments: ParsingTest.java, ParsingTest.xml, ParsingTest.xsd
>
> 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).
