failed.org.hibernate.exception.JDBCConnectionException: Error calling Driver#connect with PostGres Hibernate

Question

I keep getting this error, here are my files

hibernate.cfg.xml

    <!-- Database connection settings -->
    <property name="connection.driver_class">org.postgresql.Driver</property>
    <property name="connection.url">jdbc:postgresql://localhost:5432/postgres</property>
    <property name="connection.username">postgres</property>
    <property name="connection.password">postgres></property>

    <property name="hibernate.default_schema">hibernate_test</property>

    <!-- JDBC connection pool (use the built-in) -->
    <property name="connection.pool_size">1</property>

    <!-- SQL dialect -->
    <property name="dialect">org.hibernate.dialect.PostgreSQL82Dialect</property> 

    <!-- Disable the second-level cache  -->
    <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property>

    <!-- Echo all executed SQL to stdout -->
    <property name="show_sql">true</property>

    <!-- Drop and re-create the database schema on startup  -->
    <property name="hbm2ddl.auto">update</property>

    <mapping class="com.de.entity.Employee"></mapping>

</session-factory>

HibernateUtil.java

package com.de.config;

import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;


/**
 * Sets up the connection the DB and Hibernate
 * @author de
 *
 */
public class HibernateUtil {

    private static final Logger logger = LoggerFactory.getLogger(HibernateUtil.class);

    private static final SessionFactory sessionFactory = buildSessionFactory(); 


    private static SessionFactory buildSessionFactory() {
        logger.info("Creating Hibernate Session Factory");
        try{
            // Create the SessionFactory form hibernate.cfg.xml
            Configuration configuration = new Configuration();
            configuration.configure("hibernate.cfg.xml");
            logger.info("Hibernate Configuration loaded");
            logger.info("Configuration: " + configuration.getProperties());
            ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
            SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);
            return sessionFactory;
        } catch (Throwable ex) {
            logger.error("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }

    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }

}

Here is a better snippet of the error

09:47:23,829  WARN DriverManagerConnectionProviderImpl:93 - HHH000402: Using Hibernate built-in connection pool (not for production use!)
09:47:23,846  INFO DriverManagerConnectionProviderImpl:166 - HHH000401: using driver [org.postgresql.Driver] at URL [jdbc:postgresql://localhost:5432/postgres]

09:47:23,922 ERROR HibernateUtil:35 - Initial SessionFactory creation failed.org.hibernate.exception.JDBCConnectionException: Error calling Driver#connect

I've been trying my best to figure out what this issue is. I downloaded Navicat for Postgres and I was able to successfully connect to it using the connection url and username/password. So I narrowed out the connection information being incorrect.

Just for completion...

Well I feel like an idiot. There was a typo in the password.

<property name="connection.password">postgres></property>

I didn't realize it until I stepped through the jdbc classes and discovered the psql error.
