If you can easily see the solution on sight, you should also be able
to easily see which move it should do to reach that optimal
solution.<br>
What does logging with level TRACE print? Can you find the move it
should do in that log? What score does the log say that move has?<br>

solutionEquals/HashCode is only called with
<solutionTabuSize>, which is worthless when scaling out
(unlike entityTabuSize).<br>
A solution's equals/hashCode is never called.<br>
<br>
<entityTabuSize> should be calling the planning entity's
equals/hashcode, at least in Planner 5.5-.<br>
For Planner 6.0 I am looking into stop relying on the entity's
equals/hashcode, in case users have overwritten the default
java.lang.Object behavior in a way that's incompatible for Planner.<br>
