[rules-users] Best Solution found but latest solution does not work

[Geoffrey De Smet]

Almost nobody uses <bruteForce>, including the examples...
I 've got 1 integration test for it, NQueensBruteForceTest, (and all 
tests are green upon a release), so it should work though.

What you're describing sounds like a bug:
DefaultBruteForceSolverPhase somehow forces BestSolutionRecaller to use 
the latest workingSolution,
instead of the earlier found bestSolution, as the bestSolution.

But if that bug was real, then NQueensBruteForceTest would fail.
What version of optaplanner are you use?
If you can diagnose with some confidence that this is a bug in 
optaplanner itself, create a jira.
