When you say the app doesn't start under java 11 do you mean from within the ide?

Does it run under java 8?

There is an obvious error under java 14 error: module not found: javafx.swing. I have not used java 14 (not sure it's supported) so don't know the answer to that one I'm afraid. Have a look here : https://www.b4x.com/android/forum/t...ule-not-found-javafx-swing.118142/post-739233

Please post the compilation window text and if possible upload the project.

I'm using (and many times suggested him) OpenJDK 14.0.1 with the JavaFx folder I provided him. My javac.exe (compiler) path is:

and ALL works perfectly!
