Buggy source:

Fixed version (ground truth):

    boolean isCurrentlyFollowing=ReaderBlogTable.isFollowedBlogUrl(blogUrl);
    if (isCurrentlyFollowing == isAskingToFollow) {
      return true;
    }
  }
  final String path;
  final String actionName=(isAskingToFollow ? "String_Node_Str" : "String_Node_Str");
  if (isAskingToFollow) {
    if (hasBlogId) {
      path="String_Node_Str" + blogId + "String_Node_Str";
    }
