Unix pkill error; does wily obstruct me killing the process?

Question

I have two scripts on Unix; one that starts some processes and the other one for killing a process. At first, I ran the .sh without WILY in it and it worked perfectly; in this way, I could also ran my stopper process. However I need WILY in this so I added it to my script but this time, a message about WILY shows up instead of the first version which is perfectly normal but when I try to run my stop process it doesn't work anymore; it probably couldn't find the process with the name given. Here are my scripts:

start_scpc.sh

    export CLASSPATH='.:'
    export CLASSPATH=$CLASSPATH'./resources'

    cd lib
    for file in *.jar; do export CLASSPATH=$CLASSPATH':./lib/'$file; done
    cd ..


    # --- define WILY java options here :: Must be declared at the beginning
    ## ------------------------------------------------------------------------------
    WILY_HOME="/export/home/scpcstb/wily823"
    WILY_OPTIONS="-javaagent:${WILY_HOME}/Agent.jar -Dcom.wily.introscope.agentProfile=${WILY_HOME}/IntroscopeAgent.profile -Dcom.wily.introscope.agent.agentName=SCPC_STB"
    ## ------------------------------------------------------------------------------


    APPLICATION_NAME=SCPC_STB
    MAIN='tr.com.turkcellteknoloji.scpc.core.Main'
    JAVA_PARAM="-Xmx1g -Xbatch  -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=5563 -Dcom.sun.management.jmxremote.authenticate=false  -Dcom.sun.management.jmxremote.ssl=false"

    echo "JVM"
    echo "CHECKING $APPLICATION_NAME PROCESS"

    if [ 0 == `pgrep -fl application=$APPLICATION_NAME | wc -l` ]
    then
      echo "....................STARTING $APPLICATION_NAME........................"
      echo "Please wait"
      echo "See log files for details"

    /usr/jdks/scpcstb/bin/java -server ${WILY_OPTIONS} -Dapplication=$APPLICATION_NAME $JAVA_PARAM -cp $CLASSPATH $MAIN >> ./logs/scpcConsole.log 2>&1  &


    sleep 1    
    until [ 0 != `pgrep -fl application=$APPLICATION_NAME | wc -l` ]; do
    sleep 1
    done

    echo "....................$APPLICATION_NAME STARTED........................."

    else
    echo "$APPLICATION_NAME IS ALREADY RUNING!!!"
    fi

    exit 1

and my stop_scpc.sh:

    pkill -f application=SCPC_STB

This pkill doesn't work anymore... Any help with this would be highly appreciated, thanks.
