-------------------------------------------

             Summary: XMLConfiguration.load may throw NPE
                 Key: CONFIGURATION-641
                 URL: https://issues.apache.org/jira/browse/CONFIGURATION-641
             Project: Commons Configuration
          Issue Type: Bug
    Affects Versions: 2.1
         Environment: Java 8 / Linux
            Reporter: Claude Warren


I expect that 
{noformat}
    URL url = Test.class.getResource( "/Test.xml");     
    XMLConfiguration config = new XMLConfiguration();
    config.read( url.openStream());
{noformat}

Would read the XML file.  However it will throw a NPE at line 967

{noformat}
 private void load(InputSource source) throws ConfigurationException
    {
        try
        {
            URL sourceURL = locator.getSourceURL(); // <- NPE here
            if (sourceURL != null)
            {
                source.setSystemId(sourceURL.toString());
            }
{noformat}

I believe that testing for locator == null first will solve the problem as the 
rest of the code in the method does not appear to use it.
