    Description

      type casting exception in OptaPlanner 7.x tests which uses drl
      Caused by: java.lang.ClassCastException: class java.lang.Integer cannot be cast to class java.lang.Double (java.lang.Integer and java.lang.Double are in module java.base of loader 'bootstrap')
      The rule is:

      rule "periodSpread"
    when
        $constraintConfiguration : ExaminationConstraintConfiguration()
        $topicConflict : TopicConflict($leftTopic : leftTopic, $rightTopic : rightTopic)
        $leftExam : Exam(topic == $leftTopic, $leftPeriodIndex : periodIndex, period != null)
        $rightExam : Exam(topic == $rightTopic, period != null,
                Math.abs($leftPeriodIndex - periodIndex) < ($constraintConfiguration.getPeriodSpreadLength() + 1))
    then
        scoreHolder.penalize(kcontext, $topicConflict.getStudentSize());
end

      The problematic string is here : Math.abs($leftPeriodIndex - periodIndex) < ($constraintConfiguration.getPeriodSpreadLength() + 1))

          Bug - A problem that impairs or prevents the functions of the product. PLANNER-2618 Regression in ExaminationPerformanceTest

          • 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.
