I'm filing this because the compiler asked me to, although the error is user error.

Here's the output from the compiler.

The problem is that I passed in an argument ,foo, and assigned it to this.foo, but
I didn't have foo defined in the class.

            ^
error: An exception has occurred in the compiler; please file a bug report

what made it crash:

    int with; <---- THIS WAS SPELLED WRONG

    public void setDimensions(int width,
                              int height) {
        this.width = width;
    }

I was assigning a this.variable that didn't exist

I tried it out in a couple different places and always got the same error.

hope that make sense
