Weird error with FileHandler, java.util.logging.FileHandler

[nmvictor]

I am trying to enable logging logging for my application but it cant start because of this error

Exception in thread "main" java.lang.IllegalArgumentException
	at java.util.logging.FileHandler.<init>(Unknown Source)
	at eAdmin.EstudentAdministration.initializeProperties(EstudentAdministration.java:311)
	at eAdmin.EstudentAdministration.main(EstudentAdministration.java:269)

The section of code with which i am trying to enable the logging is

   */
    public static void main(String[] args) {
        if(args == null || args.length != 1) {
           showUsage();
           System.exit(1);
        }
        /*
         * SOME WEIRD ERROR HERE!!!!
         */
        Properties props = new Properties();
        try {
        InputStream inputStream = new FileInputStream(args[0]);
        props.load(inputStream);
        } catch(IOException ioe) {
            ioe.printStackTrace(System.err);
        }
         // Initialize the properties/configurations
        initializeProperties(props);
        BasicConfigurator.configure();
        EstudentAdministration eAdmin = new EstudentAdministration();
        eAdmin.show();
    }

 private static void initializeProperties(Properties _props) {
        try {
        logFile = _props.getProperty("LOG_FILE", DEFAULT_LOG_FILE);
        FileHandler logFileHandler = new FileHandler(logFile);
        eAdminLOG.addHandler(logFileHandler);
        } catch(IOException ioe) {
            ioe.printStackTrace(System.err);
        }

    }

Either u have empty entry in the property file or u have no entry in the property file and DEFAULT_LOG_FILE is empty
