com.sun.org.apache.xerces.internal.impl.XMLStreamFilterImpl has incorrect behaviour of hasNext() (result is always true if called more then once)

the following set of tests:

api/javax_xml/stream/AllSimpleTypesFilterTest.html#AllSimpleTypesFilterTest[testStreamEquals]
api/javax_xml/stream/DefaultNamespaceFilterTest.html#DefaultNamespaceFilterTest[testStreamEquals]
api/javax_xml/stream/NameFilterTest.html#NameFilterTest[testStreamEquals]
api/javax_xml/stream/TypeFilterTest.html#TypeFilterTest[testStreamEquals]

fail due to incorrect realization of com.sun.org.apache.xerces.internal.impl.XMLStreamFilterImpl.hasNext().

the following example hangs on mustang:

import javax.xml.stream.XMLStreamReader;
import javax.xml.stream.XMLEventReader;
import javax.xml.stream.StreamFilter;
import javax.xml.stream.EventFilter;
import javax.xml.stream.XMLInputFactory;
import javax.xml.stream.XMLStreamException;
import javax.xml.stream.events.XMLEvent;


public class sample{

public static void main(String[] args){

try{
  XMLInputFactory factory = XMLInputFactory.newInstance();
  TypeFilter f;
  java.io.File input = new java.io.File(".", "sample.xml");;

    factory = XMLInputFactory.newInstance();
    f = new TypeFilter();
    f.addType(XMLEvent.START_ELEMENT);
    f.addType(XMLEvent.END_ELEMENT);
    f.addType(XMLEvent.PROCESSING_INSTRUCTION);
    f.addType(XMLEvent.CHARACTERS);
    f.addType(XMLEvent.COMMENT);
    f.addType(XMLEvent.SPACE);
    f.addType(XMLEvent.START_DOCUMENT);
    f.addType(XMLEvent.END_DOCUMENT);

      XMLStreamReader r1 =
        factory.createFilteredReader(factory.createXMLStreamReader(new java.io.FileReader(input)), (StreamFilter)f);


    while(r1.hasNext()) {
r1.next();

System.out.println("first: R1.hasNext:"+r1.hasNext());
System.out.println("second: R1.hasNext:"+r1.hasNext());
System.out.println("third: R1.hasNext:"+r1.hasNext());
     }

System.out.println(r1);


}catch (Exception e){
e.printStackTrace();
}
}

}


with output like this:

first: R1.hasNext:false
second: R1.hasNext:true
third: R1.hasNext:true
