CLASSPATH="${CLASSPATH}:${OVTA_JAR}"
JAVA_OPTIONS="$JAVA_OPTIONS $OVTA_JAVA_OPTIONS"
echo $CLASSPATH
else
echo "Sorry, /opt/HPOV_IPA/bin/ovta_wls.sh is not readable, please investigate, bye ..."

Hi,

first tipp - comment out some lines and check if the remaining lines work.
I think here you also need a ':'
JAVA_OPTIONS="$JAVA_OPTIONS:$OVTA_JAVA_OPTIONS"
and maybe also the brackets '{' and '}' ?

P.S.
Which shell is it?

I don't think it is the code shown which causes a core dump, but rather sonething it
runs: /opt/HPOV_IPA/bin/ovta_wls.sh
And in turn that probably does not cause a dump, because shell scripts do not tempt to cause dump. It is probably a program it calls.
Try debug with print statements or use a first line:
set -x

Free advice, if you are going to use a piece of string more than once, then please put it in a variable. Otherwise it is way to easy to create spelling/maintenance errors.
IN the example the string "/opt/HPOV_IPA/bin/ovta_wls.sh" is used 3 times.
Stick it into a variable. Once.
For example:
$ovta_wls_script="/opt/HPOV_IPA/bin/ovta_wls.sh"

Good luck,
Hein.
