[jira] Created: (XERCESJ-1088) NullPointerException in SchemaDOM.processAttValue

NullPointerException in SchemaDOM.processAttValue
-------------------------------------------------

         Key: XERCESJ-1088
         URL: http://issues.apache.org/jira/browse/XERCESJ-1088
     Project: Xerces2-J
        Type: Bug
  Components: XML Schema Structures  
    Versions: 2.7.0    
 Environment: All
    Reporter: George Cristian Bina
    Priority: Critical


Parsing the following schema that contains xmlns="" in and an annotation:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="issues" xmlns="">
        <xs:annotation/>
        <xs:complexType/>       
    </xs:element>
</xs:schema>

Xerces gives a NPE with the following trace:

java.lang.NullPointerException
        at org.apache.xerces.impl.xs.opti.SchemaDOM.processAttValue(Unknown Source)
        at org.apache.xerces.impl.xs.opti.SchemaDOM.startAnnotation(Unknown Source)
        at org.apache.xerces.impl.xs.opti.SchemaDOMParser.emptyElement(Unknown Source)
        at org.apache.xerces.impl.XMLNSDocumentScannerImpl.scanStartElement(Unknown Source)

        at org.apache.xerces.impl.xs.opti.SchemaParsingConfig.parse(Unknown Source)
        at org.apache.xerces.impl.xs.opti.SchemaDOMParser.parse(Unknown Source)
        at org.apache.xerces.impl.xs.traversers.XSDHandler.getSchemaDocument(Unknown Source)
        at org.apache.xerces.impl.xs.traversers.XSDHandler.parseSchema(Unknown Source)
        at org.apache.xerces.impl.xs.XMLSchemaLoader.loadSchema(Unknown Source)
        at org.apache.xerces.impl.xs.XMLSchemaLoader.loadGrammar(Unknown Source)
        at org.apache.xerces.parsers.XMLGrammarPreparser.preparseGrammar(Unknown Source)

The problem seems to be that in the processAttValue the parameter "original" is null.

It will be great is this can be fixed for the 2.7.1 release.

Thanks,
George

Michael Glavassevich resolved XERCESJ-1088:
-------------------------------------------

    Resolution: Fixed

We weren't checking whether the namespace URI returned from the NamespaceContext is null.  Should be fixed in CVS now.
