Radu Coravu created XERCESJ-1569:
------------------------------------
Summary: NPE when validating XML with XML Schema 1.1 (but
validation is made in 1.0 compatibility mode)
Key: XERCESJ-1569
URL: https://issues.apache.org/jira/browse/XERCESJ-1569
Project: Xerces2-J
Issue Type: Bug
Components: XML Schema 1.1 Structures
Reporter: Radu Coravu
Fix For: 2.11.0
I validate an XML:
<root xmlns="http://xstest-tns/schema11_D4_3_15";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://xstest-tns/schema11_D4_3_15 npeXerces.xsd"/>
with an XML Schema 1.1:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:tns="http://xstest-tns/schema11_D4_3_15";
targetNamespace="http://xstest-tns/schema11_D4_3_15";
elementFormDefault="qualified">
<xs:element name="root">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:assertion test="/root = 'present'"
xpathDefaultNamespace="##targetNamespace" />
</xs:restriction>
</xs:simpleType>
</xs:element>
</xs:schema>
Although the schema is 1.1, it is parsed in 1.0-mode.
The NPE is like:
java.lang.NullPointerException
