The rules for + class equivalence inside jvms require that a class be identical and come from + the same class loader. I fixed the problem by repackaging the xerces.jar archive + without the org/xml/ and javax/ directories. + + Other people could have this problem when code they've written uses its own + class loader to load xerces. They may see it more, now that jdk1.4 is supplying + jaxp code. + + My repackaged xerces.jar removed: + + org/xml/ + org/xml/sax/ + org/xml/sax/AttributeList.class + org/xml/sax/Attributes.class + org/xml/sax/ContentHandler.class + org/xml/sax/DTDHandler.class + org/xml/sax/DocumentHandler.class + org/xml/sax/EntityResolver.class + org/xml/sax/ErrorHandler.class + org/xml/sax/HandlerBase.class + org/xml/sax/InputSource.class + org/xml/sax/Locator.class + org/xml/sax/Parser.class + org/xml/sax/SAXException.class + org/xml/sax/SAXNotRecognizedException.class + org/xml/sax/SAXNotSupportedException.class + org/xml/sax/SAXParseException.class + org/xml/sax/XMLFilter.class + org/xml/sax/XMLReader.class + org/xml/sax/helpers/ + org/xml/sax/helpers/AttributeListImpl.class + org/xml/sax/helpers/AttributesImpl.class + org/xml/sax/helpers/DefaultHandler.class + org/xml/sax/helpers/LocatorImpl.class + org/xml/sax/helpers/NamespaceSupport$Context.class + org/xml/sax/helpers/NamespaceSupport.class + org/xml/sax/helpers/ParserAdapter$AttributeListAdapter.class + org/xml/sax/helpers/ParserAdapter.class + org/xml/sax/helpers/ParserFactory.class + org/xml/sax/helpers/XMLFilterImpl.class + org/xml/sax/helpers/XMLReaderAdapter$AttributesAdapter.class + org/xml/sax/helpers/XMLReaderAdapter.class + org/xml/sax/helpers/XMLReaderFactory.class + org/xml/sax/ext/ + org/xml/sax/ext/DeclHandler.class + org/xml/sax/ext/LexicalHandler.class + javax/ + javax/xml/ + javax/xml/parsers/ + javax/xml/parsers/DocumentBuilder.class + javax/xml/parsers/DocumentBuilderFactory.class + javax/xml/parsers/FactoryConfigurationError.class + javax/xml/parsers/ParserConfigurationException.class + javax/xml/parsers/SAXParser.class + javax/xml/parsers/SAXParserFactory.class + + + One way to solve it would be to have the xerces kit include two separate .jar + files, one with the code included in jdk1.4 and one with the xerces-specific + code.
