java.util.Sublist throwing StackOverFlowError

We are getting occasional StackOverFlowError errors in production related to doing a SubList operation. Has anyone seen something like this before and know what could cause it?

This is the code that gets called that triggers the error:

  FacesContext context = FacesContext.getCurrentInstance();
    String newViewID = context.getViewRoot().getViewId();

    if (newViewID != null) {
     if (breadCrumbs.contains(newViewID)) {
      // Trims the list upon going back to allow for multiple back button requests.  
      // This is lightweight and not intended for a complex circular navigation.
      breadCrumbs = breadCrumbs.subList(0, breadCrumbs.indexOf(newViewID) + 1);
     } else {
      breadCrumbs.add(newViewID);
     }
    }

The result :
