> Security Level: Public(Everyone can see)
> Components: drools-planner
> Affects Versions: 5.3.1.Final

> When setting a complete solution tabu, the starting solution is not considered a Tabu making it possible to visit the same solution again.
> Consider a situation where there is construction phase followed by a local search phase. The construction phase will create a solution that will not be added to the tabu list of the local search phased.
> To fix it, I suggest to override the function phaseStarted(...) in SolutionTabuAcceptor to add solution to the Tabu map.
