When using a custom shadow variable with a reference to another custom shadow variable like in the example below:
@PlanningVariable(valueRangeProviderRefs = {"routeRange", "itemRange"},
graphType = CHAINED)
public RoutePunt getPreviousRoutePunt() {
return previousRoutePunt;
}
@CustomShadowVariable(variableListenerClass = ItemTimeUpdatingVariableListener.class, sources = {
@PlanningVariableReference(variableName = "previousRoutePunt"),
@PlanningVariableReference(variableName = "route"),
@PlanningVariableReference(variableName = "nextItem")})
public Duration getActualDuration() {
return actualDuration;
}
@CustomShadowVariable(variableListenerRef = @PlanningVariableReference(variableName = "actualDuration"))
public LocalDateTime getPlannedArrivalTime() {
return plannedArrivalTime;
}
When a corruption occurs in the plannedArrivalTime (example above) the following NPE appears.
Exception in thread "1" java.lang.NullPointerException at org.optaplanner.core.impl.score.director.AbstractScoreDirector.assertShadowVariablesAreNotStale(AbstractScoreDirector.java:415) at org.optaplanner.core.impl.solver.recaller.BestSolutionRecaller.solvingStarted(BestSolutionRecaller.java:83) at org.optaplanner.core.impl.solver.DefaultSolver.solvingStarted(DefaultSolver.java:218) at org.optaplanner.core.impl.solver.DefaultSolver.solve(DefaultSolver.java:197) at x.x.x.x.x.lambda$null$1(x.java:48) at java.lang.Thread.run(Thread.java:745)
This is caused by the VariableListenerClass which is null on referenced shadow variable
