eclipse startup-error after config cvs

[marcelino]

Hello java- community,

i'm working on SuSE 9.0 with eclipse from the distribution since 2
month without problems, but since I changed the perspective to cvs
Repository Exploring and restart it I can't run it anymore. Parallel I
tried to configure cvs and set up the environment and created the
group.
The error starting occuring starting eclipse is:

The changes I made are:

as root:
addgroup cvs
adduser to cvs (in yast)
create rep-directory
create empty rep: cvs -d /myPath/CVSROOT init
chgrp -R cvs /myPath/CVSROOT
chmod -R ug+rwx /myPath/CVSROOT

in /etc/profile.local:

unset CVSROOT
CVSROOT='/myPath/CVSROOT'
export CVSROOT

unset CVSUMASK
CVSUMASK='003'
export CVSUMASK

unset CVSEDITOR
CVSEDITOR='emacs -nw'
export CVSEDITOR

If somebody has an idea I would appreciate it
