Buggy source:
public static IAccess resolve(List<Marker> markers,IContext context,IAccess access){
  LinkedList<IAccess> chain=getCallChain(access);
  ListIterator<IAccess> iterator=chain.listIterator();

  boolean backwards=false;
  while (iterator.hasNext()) {

    curr=iterator.next();
    if (prev != null) {
      context1=prev.getType();
      curr.setValue(prev);
    }
 else {
