jedit alters user and group of file

I'm running jedit as root, to alter several system files in /etc, some of these files have different owners then root.

When I edit such a file, and save them, jedit set user to root and group to root.

Is there a option to set, that jedit keeps the file permissions?

1. Turn off 2-stage save
2. Set the number of backups to 0, to disable them

The second step is not necessary on version 5.0, which will be released this year. This is the related bug report: #1803073
