[External] : Using JavaFX on Linux can be dangerous

[PavelTurk]

Hi everyone,

I would like to warn everyone and provide some feedback regarding the 
use of JavaFX on Linux. We developed a small application and gave it to 
a small number of the customer’s employees for testing. The application 
was tested on both Linux and Windows.

We encountered serious problems on Linux. Due to bug JDK-8371781, popup 
windows are not displayed to the user, but they are still present in the 
scene. As a result, a user can click on elements in these popups without 
being able to see them, potentially triggering actions that they 
absolutely should not be able to perform.

Therefore, I decided to bring this issue to the attention of the JavaFX 
developers and warn others about the potential safety implications of 
using JavaFX on Linux.

Best regards, Pavel
