Comment 1 Andrew Clement

caused by changing from this:

public  Iterable<? extends NodeBacked> NodeBacked.findAllByTraversal(final Class<? extends NodeBacked> targetType, TraversalDescription traversalDescription) {
...
    }

to this

   public  <T extends NodeBacked> Iterable<T> NodeBacked.findAllByTraversal(final Class<T> targetType, TraversalDescription traversalDescription) {
...
    }

changed resolve in World slightly for type variables.

fixed.
