_______________________________________________________
Details:
When you start my Java-App via screen and my app tries to self-update, the
screen session just closes in the middle of it.
This is how the self-updater works:
1. Download update-jar into /downloads and make a copy of the downloaded
update-jar also in /downloads
2. Start the update-jar (which detects that it is inside the /downloads dir)
and close itself
NOTE: The I/O never closes because the update-jar inherits it.
This means that on regular windows/ubuntu terminals this works without
problem.
3. The update-jar now replaces the original jar with its copy and starts the
original (now updated) jar
