BUG: StringIndexOutOfBoundsException

[Ronald Bourret <rp...@hotmail.com>]

Namespaces and entity references don't seem to like each other. In 
particular, the following code returns a StringIndexOutOfBoundsException. If 
I remove the call to set the namespaces feature to true, or if I remove the 
entity reference from the XML document, the exception is not thrown.

-- Ron Bourret

============================
Code:

import java.io.File;
import org.apache.xerces.parsers.DOMParser;
import org.xml.sax.InputSource;
import org.w3c.dom.Document;

public class TestXerces2
{
   public static void main (String[] argv) throws Exception
   {
      String    xmlFilename = argv[0];
      DOMParser parser = new DOMParser();
      parser.setFeature("http://xml.org/sax/features/namespaces", true);

      // Parse the input file
      parser.parse(new InputSource(getFileURL(xmlFilename)));
   }

   static String getFileURL(String fileName)
   {
      File   file;
      String path, separator;

      file = new File(fileName);
      return "file:///" + file.getAbsolutePath();
   }
}

=========================================
XML Document:

<?xml version="1.0" ?>
<!DOCTYPE A [
   <!ENTITY foo '<B/>'>
]>
<A>&foo;</A>

==========================================
Output:

C:>java TestXerces2 tx2.xml
Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String 
index out of range: -1
        at org.apache.xerces.framework.XMLParser.parse(XMLParser.java:834)
        at TestXerces2.main(TestXerces2.java:18)

Thanks for the excellent bug report. It is now fixed and is 
available in CVS.
