Image class and paths relative to classpath

Are you saying you don't like the URL 'classpath:' notation or that you don't like classpath loading at all?

If the former, I don't see how one notation over the other creates any implementation issues. Can you elaborate?

If the later. Yes, you need your tool to be classpath/sourcepath aware just like an IDE. There really shouldn't be a real technical challenge on this, or any huge safety risk. It's standard Java/IDE stuff. I dont know how you'd avoid it anyway. How do you load properties files for example, or validate against the defined FXML Controller, or load custom Controls?
