this issue appeared from jaxp1.4 july30 nightly build onwards , was working with july29 nightly build !

Testcase to reproduce this issue - Test1.java

import javax.xml.stream.events.*;
import javax.xml.transform.*;
import javax.xml.transform.stax.*;


public class Test1 {

    XMLInputFactory ifac = XMLInputFactory.newInstance();
    XMLOutputFactory ofac = XMLOutputFactory.newInstance();
    
    public static void main(String args[]){
     // try{
        Test1 t1 = new Test1();
        t1.test05();
    }

    /* createXMLStreamReader(new FileInputStream()) */
    public void test05() {
        try{
            System.out.println("before ifac.createXMLStreamReader");
            XMLStreamReader reader = ifac.createXMLStreamReader(new FileInputStream("cities.xml"));
            System.out.println("after ifac.createXMLStreamReader");
         
        }
        catch(Exception e){
