This is one of the classes in that troubled existing project. If I create a new
project (in Java 15) and then switch it to Java 16, then there is no problem.
{code:java}
import javafx.scene.Scene;
import javafx.scene.layout.HBox;
import javafx.scene.paint.Color;
import javafx.scene.text.Font;
import javafx.scene.text.Text;
import javafx.scene.text.TextBoundsType;
import javafx.stage.Stage;
public class TextHeightInPixel extends javafx.application.Application {
@Override
public void start(Stage stage) {
var text = new Text("I");
text.setBoundsType(TextBoundsType.VISUAL);
text.setFont(Font.loadFont(getClass().getResourceAsStream("GT Pressura
Mono Regular Regular.ttf"), 100));
var pane = new HBox(text);
text.setFill(Color.BLUE);
var scene = new Scene(pane, 700, 400);
setPixelHeight(scene, text, 99);
stage.setScene(scene);
stage.show();
}
public static void setPixelHeight(Scene scene, Text text, int size) {
for (var i = size + 1;; i++) {
text.setStyle("-fx-font-size:" + i + ";");
var pixelReader = scene.snapshot(null).getPixelReader();
if (!(pixelReader.getColor(0, size)).equals(pixelReader.getColor(0,
size + 1))) {
break;
}
}
}
public static void main(String[] args) {
launch(args);
}
}
{code}
This is a simple program that sets the desired height in pixels.

The important message is:
{code:java}
Error: LinkageError occurred while loading main class example.TextHeight
java.lang.UnsupportedClassVersionError: example/TextHeight (class file
version 59.65535) was compiled with preview features that are unsupported. This
version of the Java Runtime only recognizes preview features for class file
version 60.65535
{code}
this indicates that either 'preview' features were enabeld by the user (= user
error) and the class should be recompiled, or NetBeans somehow messed in with
e.g. compile-on-save feature. It may indicate a broader issue, although it may
surface (in this case) on JDK16 only.
[~Michal_cat] could you please try to create a _minimal_ sample project and
attach it here ? *TextHeight* class is likely to be involved.

You're right. If the versions don't differ much, there is a chance that some
things will work without support. Anyway, when will the version with JDK 16
support be released? I mean Daily build.

When something isn't supported, i.e., JDK 16 in this case, then some things
work and some things don't. It's unpredictable. JDK 16 is not supported,
anything that works for you is great, and anything that doesn't is as expected.

I'm sorry, I didn't think of that. Anyway, I set the NetBeans runtime to JDK
16. Still, it can be run and everything seems OK. I can create a new project
that also works. And the second existing project works, for which I only
changed the version. So then I don't understand how he can't support it when
everything (except my specific project) seems to work?
