-----------------------------------------

             Summary: A custom phase which initializes the solution but doesn't provide a better solution than the original should not get reverted
                 Key: JBRULES-3577
                 URL: https://issues.jboss.org/browse/JBRULES-3577
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-planner
            Reporter: Geoffrey De Smet
            Assignee: Geoffrey De Smet


DefaultSolver.runSolverPhases() will go through each phase, and will revert
the changes if they're not better. Or, more exactly, here are lines 191-193:

            if (it.hasNext()) {
                // solverScope.setWorkingSolutionFromBestSolution();
            }

Now, if this involved setting the planning variables for the first time,
those will be reverted.
