java - slick2d - statebasedgame error - No OpenGL context found in the current thread

I've just started playing with slick2d's state based game structure. I've set up the main class as follows

    public static final int newMenu = 0;

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        AppGameContainer appgc;
        try {
            appgc = new AppGameContainer(new StateBased("StateBased Test"));
            appgc.setDisplayMode(640, 360, false);
            appgc.start();
        } catch (SlickException e) {
        }
    }

    public StateBased(String name) throws SlickException {
        super(name);
        this.addState(new NewMenu(newMenu));
    }

    @Override
    public void initStatesList(GameContainer gc) throws SlickException {
        this.getState(newMenu).init(gc, this);
    }

now the new menu class so far has

    private final int state;
    private final Image bg;
    private final static String directory = "Images/StartScreen/";

    public NewMenu(int state) throws SlickException {
        this.state = state;
        bg = new Image(directory + "loadbg.png");
    }

but i'm getting at error at the "bg=new image" line. "No OpenGL context found in the current thread." I'm confused since I haven't got this when using basicgame instead of statebasedgame

Can anyone help me solve this

This is the full error

Fixed by moving the code from the constructor to the init method
