Verify Error

[Lord Voldemort]

I'm getting an error for a class that worked perfectly fine before.

Exception in thread "AWT-EventQueue-0" java.lang.VerifyError: 
(class: pong/Ball, method: <init> signature: (II)V) Constructor must call super() or this()

It says the problem shows up with this line:

allBalls.add(new Ball(200, 200));

However my constructor for balls is as follows: (It does call super()... )

    public Ball(int x, int y) {
        super(x, y);
        truX = (double) x;
        truY = (double) y;
    }

Again I used this code before with no changes and it worked perfectly. I also searched a few older threads and I cleared the cache, but that didn't fix my problem (or maybe I did it wrong?)

Impossible. Something must have changed. Try deleting all your .class files and compiling again.
