javafx Error

[JoAllg]

As mentioned in #15 it is not possible to start the downloader with JDK15 on Win10 64bit and possibley other versions too.
'''

It seems that problem can be bypassed with the "--add-modules javafx.web" flag as mentioned by vonHartz #15, however that probably works only on linux where a compiled version of javafx.web is in the shared libaries.

I guess the reason is, that JavaFX is not part of JDK/JRE since JDK11. I tried downloading the current version from https://gluonhq.com/products/javafx/ but were not able to use it.

edit: This error previously described in this comment was totaly my fault :-)

are you sure you can start the java gui out of your wsl?
--> Caused by: java.lang.UnsupportedOperationException: Unable to open DISPLAY

You have got a very good point there! Gotta install such features first.

As mentioned in the readme, the current JDK is JDK 8, preferably with javafx included.
To overcome this issue in the future and make it ready for JDK 11 and upcoming LTS versions, see #51
