Summary: ClassCastException Double -> Integer in Interactions Pane

Initial Comment:
Welcome to DrJava.  Working directory is /rhel5pdi/home/mricken/Desktop/gss
> double multiplier = 2
> int backoff = 1000;
> int sum = 0
> int iteration = 0;
> ++iteration; sum += backoff; backoff *= multiplier; System.out.println("Iteration "+iteration+" -> total backoff = "+sum)
Iteration 1 -> total backoff = 1000
> ++iteration; sum += backoff; backoff *= multiplier; System.out.println("Iteration "+iteration+" -> total backoff = "+sum)
> 


This, however, worked:
