    Description

      Executing a rule containing accumulate max, eg:

      rule AccumulateMaxDate
  when
  $max1 : Number() from accumulate(
  StockTick(isSetDueDate == true
        ,$time : dueDate);
       max($time.getTime().getTime()))
  then
  end

      fails with a NPE at runtime if the StockDate.dueDate field is null:

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
