Debugging JavaFX

[Tom Eugelink]

I think I saw that one of the argument for not providing debug symbols was size... If there is anything I would not quickly compromise on nowadays is size. Even my smartwatch has gigabytes of internal storage. If size is an issue for an application, it is usually not caused by including debug symbols in a jar.
