> Not confirmed yet that this is a drools bug, but it probably is :)
> Jiri is isolating.
> To reproduce:
> Use https://github.com/droolsjbpm/optaplanner/pull/234
> and run CloudShuttleGatheringPerformanceTest.
> {code}
> java.lang.IllegalStateException: Impossible VariableListener corruption: the expectedWorkingScore (0hard/-397050soft) is not the workingScore  (-2000000000hard/-397050soft) after all VariableListeners were triggered without changes to the genuine variables.
> But all the shadow variable values are still the same, so this is impossible.
