val scoreManager = ScoreManager.create<SolutionClass, HardMediumSoftLongScore>(solverFactory)
val explanation = scoreManager.explainScore(solution)
println(explanation)

      output:

      Explanation of score (0hard/0medium/-240soft):
    Constraint match totals:
        0: constraint (constraint 1) has 0 matches:
        0: constraint (constraint 2) has 0 matches:
        0: constraint (constraint 3) has 0 matches:

      When switching the constraintStreamImplType to DROOLS we obtain the expected output

      Expected behavior

      When configuring constraintStreamImplType.BAVET the scoreManager's score explanation should yield the same output as when configuring constraintStreamImplType.DROOLS

      Actual behavior

      The score explanation is empty when using BAVET. When using DROOLS a proper, correct score explanation is created.
