> I am seeing an odd behavior with the latest code in the main trunk (Directory revision: 1358535). The solver throws "NoFeasibleSolutionException" for a problem which has a feasible solution. Just by commenting out the last constraint, we get a feasible solution. And for that solution, the constraint in question does not seem to be playing a role.
