> On the solr-user mailing list, Ebisawa & Alex both commented that they've noticed bugs in the grouping code when some documents don't have values in the grouping field.
> In Ebisawa's case, he tracked this down to what appears to be some bugs in the logic of the "compareSameType" method of some of the MutableValue implementations.
