JavaFX: Why does stage.setResizable(false) cause additional margins?

Question

This small JavaFX test application

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
import javafx.sce         


        

Answer 1

As already commented, this different behaviour of !/resizable smells like a bug (somebody might consider filing an issue ;-)

A shorter (than sizing manually) way around is to explicitly fit the stage to the scene:

primaryStage.setScene(scene);
primaryStage.setResizable(false);
primaryStage.sizeToScene();

Just noticed that this works for jdk8, but not jdk7.

For convenience, a bug update: the original report filed by jewelsea was closed as a duplicate of (in new coordinates) https://bugs.openjdk.java.net/browse/JDK-8089008 - still open, commented to be win-only.
