> When computing statistics using the statistics component, the value for max may be reported incorrectly if the maximum value does not lie in the first shard.
> This is where the problem is:
> {code:title=StatsValuesFactory.java|borderStyle=solid}
> @Override
> protected void updateMinMax(Date min, Date max) {
> if(this.min==null || this.min.after(min)) {
> this.min = min;
> }
> if(this.max==null || this.max.before(min)) {
> this.max = max;
> }
> }
> {code}
> Attached is a one-line patch which fixes this issue.
