java jedis (redis) cannot connect

I'm trying to connect to Redis using Jedis in my java application. I'm instantiating a JedisPool object, and when I get the resource, it throws an exception saying it cannot return the resource. What is weird though is if I just instantiate a Jedis object, it connects without problems, and I can change data.

Here's my RedisDatabase class:

package me.joeleoli.proxylink.database;import me.joeleoli.proxylink.ProxyLink;import redis.clients.jedis.Jedis;import redis.clients.jedis.JedisPool;public class RedisDatabase {    private JedisPool pool;    public RedisDatabase(String host, int port, String password) {        ProxyLink.getInstance().getLogger().info("Attempting to establish Redis connection "+ host +":"+ port);        this.pool = new JedisPool(host, port);        try (Jedis jedis = this.pool.getResource()) {            if (password != null && !password.equals("")) {                jedis.auth(password);            }            jedis.select(0);            jedis.close();        }    }    public JedisPool getPool() {        return this.pool;    }}

Here's my error:
