Hibernates-4.2 -Initial SessionFactory creation failed.java.lang.ExceptionInInitializerError c.C.S.C.D.D.DBConnector.sendQuery.173 - nullpointerexception

Question

below is the snippet code from my Java file but after printing label:1 , its giving me exception.
try{
logger.debug(Logger.formatLog("label:1"));
org.hibernate.cfg.Configuration con = new Configuration();
logger.debug(Logger.formatLog("label:2"));
File hiberConfFile=new File("/cfg/hibernate/hibernate.cfg.xml");
//I am on Unix Env and directory structure is RUN/cfg and RUN/lib and my java file is in lib dir ,However I have not got any kind of parsing or FileNotfoundException.
logger.debug(Logger.formatLog("label:3"));
con.configure(hiberConfFile);
logger.debug(Logger.formatLog("label:4"));
con.setProperty(USERNAME, dbInfo.getUsername());
logger.debug(Logger.formatLog("UserName:" + con.getProperty(USERNAME)));
con.setProperty(PASSWORD, dbInfo.getPassword());
logger.debug(Logger.formatLog("PASSWORD:" + con.getProperty(PASSWORD)));
con.setProperty(URL, ORACLE+dbInfo.getHost()+":"+dbInfo.getPort()+":"+dbInfo.getSid());
logger.debug(Logger.formatLog("Connection URL:" + con.getProperty(URL)));
factory =con.configure("hibernate.cfg.xml");
serviceRegistry = new ServiceRegistryBuilder().applySettings(con.getProperties()).buildServiceRegistry();
factory = con.buildSessionFactory(serviceRegistry);
factory=con.buildSessionFactory();
Session session = factory.openSession();
Transaction tx = session.beginTransaction();
results = session.createQuery(query).list();
tx.commit();
}catch (Throwable ex) {
logger.debug(Logger.formatLog(("Initial SessionFactory creation failed." + ex)));
ex.getCause().printStackTrace();
}
Getting below Error before creating Configuration Object in Hibernates after Label:1
Initial SessionFactory creation failed.java.lang.ExceptionInInitializerError c.C.S.C.D.D.DBConnector.sendQuery.173
