For me, the output is just like it is for you:

When i select this program in VisualVM, and turn the screen off, nothing
happens.
But when i maximize the test window, and turn the screen off, then
exceptions like this are generated:
```

Somehow the Exceptions say NetBeans even though i made sure to close
NetBeans.
As for NetBeans: Widowing NetBeans does not protect it from the bug (at
least not for me).
As for VisualVM: Windowing VisualVM does not protect it from the bug. When i
select no program to profile, VisualVM does not output anything when i turn the
screen off. When i select the test program, or VisualVM as target for the
profiler, the following exceptions are generated:

```
So i don't know if these Exceptions are form the test program or VisualVM.
Unfortunatley i don't know how to get the test program's exceptions without
VisualVM.
Journal while i turn the screen off:
```
journalctl -b --follow
