Hi Joe, Ok that is not good. A took a look at it and this would mean that the variable docHeadCollapseGroupAssoc (declared at line 80 in FieldValueCountCollapseCollectorFactory) is null. I always thought that the variable was set, but that is not the case when no documents are being collapsed. I will update the patch shortly.
