XMLErrorReporter isn't set in XMLParserConfiguration when using
org.apache.xerces.parsers.XML11Configuration
------------------------------------------------------------------------------------------------------------
Key: XERCESJ-1532
URL: https://issues.apache.org/jira/browse/XERCESJ-1532
Project: Xerces2-J
Issue Type: Bug
Components: XNI
Affects Versions: 2.11.0
Environment: jdk 1.6.0
Reporter: Tom Coenen
Priority: Minor
public class XNIEncodingDetector extends XMLDocumentParser
{
public static void checkEncodingDecl(XMLInputSource document) throws
XNIException, IOException
{
XNIEncodingDetector parser = new XNIEncodingDetector();
parser.parse(document);
}
}
with the following JVM system property set:
-Dorg.apache.xerces.xni.parser.XMLParserConfiguration=org.apache.xerces.parsers.XML11Configuration
This results in:
Exception in thread "main" java.lang.NullPointerException

This can be fixed by adding the following lines:
XMLErrorReporter errorReporter = new XMLErrorReporter();
parser.fConfiguration.setProperty(Constants.XERCES_PROPERTY_PREFIX+Constants.ERROR_REPORTER_PROPERTY,
errorReporter);
