NPE on getAnnotation() for not present in schema datatype
---------------------------------------------------------
Key: XERCESJ-1149
URL: http://issues.apache.org/jira/browse/XERCESJ-1149
Project: Xerces2-J
Type: Bug
Components: XML Schema datatypes
Environment: All
Reporter: Radu Coravu
Priority: Minor
Run the following code:
String content = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
"<xs:schema xmlns:xs=\"http://www.w3.org/2001/XMLSchema\";
targetNamespace='ns'>\n" +
" <xs:element name=\"personnel\"/>\n" +
"</xs:schema>";
XsModelCreator creator = new XsModelCreator();
SymbolTable symbolTable = new SymbolTable();
InputSource src = new InputSource(new StringReader(content));
src.setSystemId("fake");
// Preparser setup.
XMLGrammarPreparser preparser = new XMLGrammarPreparser(symbolTable);
preparser.registerPreparser(XMLGrammarDescription.XML_SCHEMA, null);
// Selects the grammar pool.
XMLGrammarPool grammarPool= new XMLGrammarPoolImpl();
preparser.setGrammarPool(grammarPool);
preparser.preparseGrammar(XMLGrammarDescription.XML_SCHEMA, new
XMLInputSource(
src.getPublicId(),
src.getSystemId(),
null,
src.getCharacterStream(),
src.getEncoding()));
XSModel xsModel = creator.newXSModel(grammarPool);
XSElementDeclaration elemDecl = xsModel.getElementDeclaration("personnel",
"ns");
XSComplexTypeDefinition typeDefinition = (XSComplexTypeDefinition)
elemDecl.getTypeDefinition();
XSWildcard attributeWildCard = typeDefinition.getAttributeWildcard();
attributeWildCard.getAnnotation();//This should throw the NPE.
As you can see, the personnel element has no associated data typed but it is
mapped by default to anyType in the Xerces structure.
This NPE also happens when getAnnotation() is called for nodes of types
XSElementDeclaration, XSWildcard, XSModelGroup which do not actually appear in
the schema (they can be obtained by exploring the XSComplexTypeDefinition of
the anyType).
