Program started by bash works, program started by rc.local shows problem

Hello everyone,

I'm using Java and the Java Curses Library (
http://sourceforge.net/projects/javacurses/ ) which is some kind of
wrapper for the ncurses library. If I start my program from the bash, I
don't have any problems. As my program is some kind of setup program, I
want to start it from the /etc/rc.local on an Ubuntu 10.04.4 LTS 32-bit
system (libncurses5 5.7+20090803-2ubuntu3 depending on lic6 >= 2.4). But
if I do that the program shows some odd problems: The "rendering" of the
screen is not correct. The shadow of my windows is on the left border on
the screen instead of in the column before the last column. And a few
other things are also upside-down.

I already opened a bug at the Java Curses Library website:
There I also added a screenshot which shows the problem.

As I didn't know if the problem was caused by that library or the
ncurses library, I did some debugging: I created a log containing every
move() and addch() (means the y and x coordinates as well as the
character which was drawn). I compared the logs from the program startet
from the bash and the program started by the rc.local. They were
identical - in size and content. Means the Java Curses Library does the
absolutely identical ncurses calls in both cases. So I guess it is a bug
or problem within the ncurses or one of the libraries that are used by

Did someone have similar trouble in the past? Is there any bugfix or
workaround available?
