NullPointerException when loading FXML file - javafx-8

Question

So, Ive done it many times without problem and yet this time when I moved fxml and its controller from one project to another I cannot load it. Directory to fxml is fine, directory to controller in fxml file is also good, and I dont see why theres a problem to load it.
