> When a stream is keyed and time window applied, a single object is being reused among the different keyed streams. I am pasting the essence of my test code with the full version attached.
> {code:scala}
>     source
>       .keyBy( x => x.elementNumber)
>       .timeWindow(Time.milliseconds(1))
>       .apply(new WindowCounter())
> {code}
> In this example a single WindowCounter object is being created. Please correct me if this is not really a bug.
