----------------------------------------
Summary: NullPointerException when parsing an instance that has a
schema with inheritable attribute
Key: XERCESJ-1583
URL: https://issues.apache.org/jira/browse/XERCESJ-1583
Project: Xerces2-J
Issue Type: Bug
Components: 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-------------------
<BookStore xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="schema.xsd">
</BookStore>
-------------------------------------------------------
---------------------schema.xsd-----------------
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:element name="BookStore">
<xs:complexType>
<xs:attribute name="lang" inheritable="true" type="xs:string"/>
</xs:complexType>
</xs:element>
</xs:schema>
