Shell script won't run correctly when called in a while loop

Question

the following shell script reads a file but returns an error when executing esscs.sh: Error: Could not find or load main class a

cd /u01/oracle/essbase/products/Essbase/EssbaseServer/bin/cli/
while read application; do
        if [[ $application = "" || $application = "#"* ]]
        then
                continue
        else
                ./esscs.sh login -user usr -password xxx -essbaseurl https://bla/essbase
                ./esscs.sh lcmexport -application $application
        fi
done < /tmp/exportLCM_applications.txt

The following shell script works just fine:

cd /u01/oracle/essbase/products/Essbase/EssbaseServer/bin/cli/
./esscs.sh login -user usr -password xxx -essbaseurl https://bla/essbase
./esscs.sh lcmexport -application hardcodedapp

This is the content of esscs.sh which an Oracle command line utility for Essbase (cli):

#!/bin/sh

export ERR_MSG_JAVA_REQUIRED="Install JDK8 and set JAVA_HOME variable to JDK8 installed location"

if [ -z "$JAVA_HOME" ]
then
    echo
    echo $ERR_MSG_JAVA_REQUIRED
    echo
    exit 1
fi

export JAVA_VERSION=$("$JAVA_HOME/bin/java" -version 2>&1 | awk -F '"' '/version/ {print $2}')

if [[ "$JAVA_VERSION" < "1.8" ]]
then
    echo
    echo You are using older java version $JAVA_VERSION
    echo $ERR_MSG_JAVA_REQUIRED
    echo
    exit 1
fi

I resolved the issue by reading the documentation which says:

To execute multiple CLI commands, add them to any shell script and execute it. In any script you run that contains CLI commands, Oracle recommends you include the following directive before the CLI login statement: For Windows: set ESSCLI_ID=%USERNAME%%random% For Linux: export ESSCLI_ID=whoami$PPID This helps store session information and prevent execution errors when multiple scripts are run concurrently.
