[jira] [Created] (XERCESJ-1589) NullPointerException when parsing
an instance that has a XSD 1.0 schema with 'defaultOpenContent' element
Octavian Nadolu created XERCESJ-1589:
----------------------------------------
Summary: NullPointerException when parsing an instance that has a XSD 1.0 schema with 'defaultOpenContent' element
Key: XERCESJ-1589
URL: https://issues.apache.org/jira/browse/XERCESJ-1589
Project: Xerces2-J
Issue Type: Bug
Components: XML Schema 1.0 Structures, XML Schema 1.1 Structures
Affects Versions: 2.11.0
Reporter: Octavian Nadolu
If I parse the instance.xml file using the following java code, I get an NullPointerException. I tested on the xml-schema-1.1-dev branch.
----------Java code-----------------------
XMLReader parser = new org.apache.xerces.parsers.SAXParser();
parser.setFeature(Constants.XERCES_FEATURE_PREFIX + Constants.SCHEMA_VALIDATION_FEATURE, true);
parser.parse("file:/C:/instance.xml");
--------------------------------------
-----------------instance.xml-------------------
<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="schema.xsd"/>
-------------------------------------------------------
---------------------schema.xsd-----------------
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:defaultOpenContent mode="suffix">
<xs:any/>
</xs:defaultOpenContent>
<xs:element name="root"/>
</xs:schema>
--------------------------------------------------------
-----------NullPointerException -------------------------------
Exception in thread "main" java.lang.NullPointerException

---------------------------------------------------------------------------
It seems that in the XSDHandlerXerces.buildGlobalNameRegistries(), the method XSDComplexTypeTraverser.traverseOpenContent(Element, XSDocumentInfo, SchemaGrammar, boolean) is called even if the current schema version is 1.0. For 1.0 this method should not be called.
Also the XSAttributeCheckerXerces.checkAttributes(Element, boolean, XSDocumentInfo, boolean) method can return null in some cases, maybe you should check that the attributes array is not null before using it.
