General questions and concerns re B4X

Non-UI applications are not based on JavaFX

Yes, you're right. I'm currently running non-ui apps on raspberry pi and it works very well. So what are the non-ui based on? Java?

 

[Erel]

It is based on Java.

Both Java and the JavaFX will be supported for a long time. Even if Oracle will stop developing JavaFX they will maintain it.

Let's keep in mind that B4X is part of the (highly human-readable) BASIC family of languages.
This makes your source code easily re-writable in any other language.
As long as you're not depending too heavily in closed-source libraries, you should be fine.

In my opinion, in the even of a catastrophe, it's way more important to have your source code backed-up, sanitized and well commented.
