NullPointerExceptions during startup. They are caught by calling class, so not major but still, we do not want to log warnings for normal things that can happen.

There is a null check in AdvancedQueueSorterQueueListener.onEnterBuildable() but not in the other three event methods in the class.

In AdvancedQueueSorter I see newer code that might have fixed this?
