Dear all,
I’ve been working with a Raspbian CLI environment for a while and
notice some unexpected behavior from AWT.Robot.
Java registers the Raspbian CLI as a headless environment even though
it can be accessed directly through a keyboard and mouse (I did as well).
When fooling the java environment by setting the headless property to
false it throws X11 errors because it relies on an X server to do the
IO stuff.
This is the part where I believe AWT can be improved.
Yes I understand AWT exists for creating a GUI and CLI is not
considered a GUI.
Yes I understand and agree that because using a CLI some AWT related
stuff should not work.
Even though this is the case there already exists some exceptions of
using AWT in a headless environment as described by Oracle:
https://www.oracle.com/technical-resources/articles/javase/headless.html
<https://www.oracle.com/technical-resources/articles/javase/headless.html>
(I’m assuming OpenJDK shares this behavior but I didn’t test this).
I suggest the following improvements to the AWT.
* Don’t make IO simulation classes like AWT.Robot rely on the
X-Server but make it work directly on the OS IO system.
o https://pypi.org/project/keyboard/
<https://pypi.org/project/keyboard/> is a great example on
how you could do this (albeit written in python).
* Separate the headless exception into headless and a new
CLIEnvironment exception.
Because the AWT is part of the Java Foundation Classes I’m writing
this to you.
Hopefully you find my feedback useful.
Kind regards,
Sjoerd Brauer
