             Summary: RETE score corruptions: NQueens, Exam set 3
                 Key: DROOLS-142
                 URL: https://issues.jboss.org/browse/DROOLS-142
             Project: Drools
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
            Reporter: Geoffrey De Smet
            Assignee: Mario Fusco


To reproduce, run NQueensSolveAllTurtleTest with "-DrunTurtleTests=true":
{code}

java.lang.IllegalStateException: Score corruption: the workingScore (-3) is not the uncorruptedScore (0):
  Score corruption analysis could not be generated because either corrupted constraintMatchEnabled (true) or uncorrupted constraintMatchEnabled (false) is disabled.
  Check your score constraints manually.

Also run ExaminationSolveAllTurtleTest and hack it to run only exam_comp_set3 (which is the only one that fails):

Note: the exam one might be due to the custom initializer inserts the same entity twice problem.


Ping me when you have time to work on this (It's RETE not PHREAK - PHREAK is ok) and I 'll isolate the nqueens one.
