[jboss-jira] [JBoss JIRA] (JBRULES-2213) When the decider doesn't pick a move, the DefaultLocalSearchSolver shouldn't terminate by exception by try again, especially with relativeSelection on

Geoffrey De Smet commented on JBRULES-2213:
-------------------------------------------

This issue is partially obsolete now that using minimalAcceptedSelection, which means this can only occur if there are no accepted moves at all (of ALL possible moves).

Fixing this in 2 ways:
- If all moves have been tried and the forager doesn't have an accepted move, it WARNs and returns the best unaccepted move.
- If the decider returns a null nextStep (which basically means there are no moves at all), the local search solver will terminate itself.

> a random bad relativeSelection could select only moves that are tabu
> that no reason to stop, because the next relativeSelection could be great.
