Description
When an xsd that contains annotations is validated with the feature "http://apache.org/xml/features/validate-annotations" enabled, validation fails throwing a NullPointerException:
Exception in thread "main" java.lang.NullPointerException at com.sun.org.apache.xerces.internal.impl.XMLEntityManager.reset(XMLEntityManager.java:1525) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.resetCommon(XML11Configuration.java:1051) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:838) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:805) at com.sun.org.apache.xerces.internal.impl.xs.traversers.XSDHandler.validateAnnotations(XSDHandler.java:685) at com.sun.org.apache.xerces.internal.impl.xs.traversers.XSDHandler.parseSchema(XSDHandler.java:665) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaLoader.loadSchema(XMLSchemaLoader.java:612) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaLoader.loadGrammar(XMLSchemaLoader.java:571) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaLoader.loadGrammar(XMLSchemaLoader.java:537) at com.sun.org.apache.xerces.internal.jaxp.validation.XMLSchemaFactory.newSchema(XMLSchemaFactory.java:266) at javax.xml.validation.SchemaFactory.newSchema(SchemaFactory.java:649)
Following code snippet to reproduce:
SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
// "http://apache.org/xml/features/validate-annotations"
factory.setFeature(Constants.XERCES_FEATURE_PREFIX + Constants.VALIDATE_ANNOTATIONS_FEATURE, true); factory.newSchema(new File(XSDValidator.class.getResource("testxsd.xsd").getFile()));
