Selenium Java, class to run same setup across tests

I had started at this original post This has been very enlightening to read. I am in the same situation and have been trying to use this as a guide. Unfortunately, I am getting a java.lang.NullPointerException which I know why, its because the page isn't getting loaded but I am not sure why.

Here is my base test class:

import java.io.IOException;
import java.util.concurrent.TimeUnit;

import org.junit.After;
import org.junit.Before;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class IRIS_Firefox_Test_Base {
    static WebDriver driver;
    static String baseURL;
@Before
    public void setup() throws IOException{
        baseURL = "http://localhost:3006";
        driver = new FirefoxDriver();
        driver.manage().timeouts().implicitlyWait(30,  TimeUnit.SECONDS);
        driver.manage().window().maximize();
        driver.get(baseURL);
    }
@After
    public void closeFireFox(){
        driver.quit();
    }
}

And my test:

import java.io.IOException;
import org.junit.Test;

import pageObjects.Login_Page;

public class POM_TC extends IRIS_Firefox_Test_Base {
    @Test
    public void login() throws IOException{ 
        super.setup();
        Login_Page.loginInput(driver).sendKeys("scornell");
        Login_Page.passwordInput(driver).sendKeys("password");
        Login_Page.loginBtn(driver).click();
    }
}

I'm not really a well versed java programmer, my background is more JavaScript and C#(not a lot there either though). Maybe I'm missing something simple.

Here is my stack trace:
