A DESCRIPTION OF THE PROBLEM :
If your'e having a while loop with break conditions placed directly after a FileChooser.openDialog Method in the main thread of Java FX, the FileChooser will close as recently as the while-loop has ended. Under Windows, with the same steps, the file chooser closes directly after file choosing(while loops was still running!).


(I know, its not well programming style to use a while loop in the javafx main thread!)


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
First, create a class which extends from Application. Implements all methods, which are needed to launch the application.

Next, place a FileChooser in the start method and use it to save and or load a File (FileChooser.showOpenDialog method meant). Place directly after this method a whileLoop with break conditions.

Finally, run the programm!

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
If you selected a File the filechooser will close as recently as the while loop has ended and not as recently as you have choosen a file.
ACTUAL -
On windows I have no problem, under Linux the file chooser closes after the while loop has finished.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
No error messages.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
public void start(Stage primaryStage){
                FileChooser chooser=new FileChooser();
chooser.showOpenDialog(new Stage());
//Doing something big, which takes time
                int i=10000;
while(i>0){
i--;
                }
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
You can solve this temporary if you're using the Method YourePrefferedStageNameForTheFileChooser.show() after the openDialog Method and before the while-loop. If done like that, the file chooser will close regardless of wheter there's the while loop or not.

SUPPORT :
YES
